Zenith Rebuild - My First Carby Project
 

So, here I am, 2 Zenith 40 Tin carbies purchased a few years ago and I want to strip and rebuild - I know nothing about these what am i doing!! But have the workshop manuals, other documentation and of course all the useful information on this site contributed by many Zenith fans over the years. I'm half way through an engine, completed my Sporto rebuilds a while ago, so this can't be that hard.

I had a couple of years earlier purchased a 3.0L 930/16 from another Pelican which included SSI’s, Dansk muffler and while I could have installed PMO’s I felt I had more to learn by rebuilding the Zeniths and using them on the engine.

I purchased these locally and they appeared in reasonable condition. I would install new Jets, new Venturi, remove the Auxiliary Unit, install new gaskets, O-rings and the like.

I started with these

and ended the project with these, all new jets, gaskets, o-rings, a new float, new 34mm venturi, air filters and other new bits

http://forums.pelicanparts.com/uploa...1392889771.jpg

and this is the story of how I got there!!

Removing the top and the auxiliary unit which I would not replace. Removing the top cover and intake trumpets and lid (shown below) exposes the float chambers, all pretty dirty in here, and a tired worn out gasket. This was the first time I had taken to any Carburettor so I was careful in the disassembly and numbered and labelled each part as it was removed. I’d read that the aux unit is not really needed and intended not to install this once the rebuild was complete. The bolt holes and fuel ports will need to be plugged later

The accelerator jets (injection pipe) are held in place by an o-ring and these too would be replaced. Once the jet is removed there is a small Pin, to control fuel flow I guess, which at first I could not see. That was until I tipped the carby upside down and one fell out!!

The retaining clips holding the booster in came out with a little help from a small screw driver and some gentle pulling of the booster. These clips also would be replaced, one broke during this process

With the boosters and venturi removed, i then took the threaded plugs, Idle mixture control screw, Idle speed adjusting screen and noted the auxiliary fuel inlet that would later be plugged.

Thanks.

Main jets removed, as I said I'm tagging stuff as I remove it and numbering the parts according to the diagram in the workshop manual. Remember this is all new to me and at this stage of the project i'm unsure of what I will re-use or replace so I am trying to keep everything in order and documented, might be a bit over the top but it's all a learning curve.

Accerator pumps - there are 3 of these, one for each throttle/venturi combination and they consist of a plunger, diaphragm and spring that is activated by small fingers on a rod that runs the length of the carby. The rod is operated by wheel/cam on the throttle lever. As I understand it and can see by way of experimentation these are activated when the throttle is open suddenly and provide extra fuel via the injection pipe. The chambers behind the diaphragm are filled with fuel fed from the float bowl and channels seen in the body.

Excellent thread, Shane! This is on my to-do list. Mine are working fine, I guess, but could no doubt benefit from some cleaning and little upgrades. Need to get back in there and install the thermal insulators too..

I'll look forward to the rest of your project.

Excellent documentation!
Thank you for the share.

Float removal - well these are a bit tricky, I started with the float level needle valves and 2 threaded plugs that sit on top of these. As usual one threaded plug and needle valve came out easy, the second was, well shall i say a disaster. It would not budge no matter what I tried. Soaked in WD40 and CRC first I burred the edges, these are soft brass bolts! Then I tried bolt removers, and you see the results!!

Oh dear now what, some gentle tapping with a socket extender on the remaining ridge and it finally came out. A new bolt needed obviously but no damage done to the body, except in the process I broke a float bowl! Maybe would have been a good idea to remove them first, next time. New bowl and bolt added to parts list

http://forums.pelicanparts.com/uploa...1392970272.jpg

The threaded plug at the base near the idle mixture screws are difficult to remove as well, but with patience and square drive screw driver and a lever I managed to get them out - 1 fatality, burred bolt head slot! more additions to the parts list!

Removing the float bowls is also rather tricky without special tools, I found that I could not get proper leverage on the screws that hold these in place so manufactured an L shaped screw driver out of flat metal, that did the trick.

Main fuel lines removed as well. I note on the parts diagram there are small brass filters that surround the brass bolt inside the sphere of the fuel line, these are missing and subsequent enquires recommended these are not required.

I've tried unsuccessfully to remove the actual throttle discs from the throttle rod running through the 3 carbies, the screws holding them in place are dirty so I will clean first and see how this go after that now that I this one all in bits.

I am limited on space so will clean this one up, and re-assemble before tackling the other triple throat.

next cleaning.....

Cleaning - what a saga, something that seems so simple, well at least on Youtube and with chemicals I just can't seem to find here. I could have taken to specialist but wanted the experience myself, so i persevered. Asked the guys at the local vintage car shop for ideas, browsed the net etc.

I started with the manifolds, these were coated in black paint, well not real paint anyway! we suspect now that the job is done they had a coating of POR-15. I soaked the manifolds in a chemical bath at the mechanics for 2 days then attached them with a sandblaster (glass beads) and after 20 minutes hardly moved an inch or two from the surface. This was going to be hard. So more soaking another day or 2, more glass bead blasting, soaked in paint remover. I have my own sand blaster and gave that a go after further soaking, eventually many hours later and slight pitting in one area of the manifold enough of this stuff was removed to allow a new coat of paint. Silver this time.

I soaked the carby bodies in petrol, brushed, wiped with fine steel wool and eventually soda blasted them, washed with carby cleaner. The results while not professional are pleasing and the internals look much better. These shots taken part way through soda blasting show improvement, more to come.

http://forums.pelicanparts.com/uploa...1392972316.jpghttp://forums.pelicanparts.com/uploa...1392972441.jpg

After soda blasting I soaked the body in water, this dissolves the soda in the small fuel channels, but a detailed inspection revealed this was not completely so. I used fine plastic needle from a cleaning brush and the air compressor to ensure all the channels were clean. In a room with a single bright light I found its possible to visually confirm that the channels are clear.

All other bits got a clean but many will be replaced with new pieces. I'm not that happy with the external finish, that nice gold colored zinc finish would have been nice but couldn't find anyone local that was prepared to do it. I'd happily take them apart another day and get that done.

The cleaning took forever, and while that was going on I was ordering all the new bits and pieces i wanted.

New 34mm Venturi, manifold insulation gaskets, 0.5mm injection pipes (not standard 0.3mm) sourced from the UK

I had purchased the rebuild kits sold here, but frankly found them not that useful. The gaskets between the manifold and base simply did not fit and other components, o-rings etc just did not work.

Most if not all other parts came from alfa1750 (ebay), I found him very good and reliable and the stuff I ordered turned up. I would recommend him if you are looking for bits.
There is lots of discussion on jet size so I decided to get various sizes and install the most recommended combination I could find in the many threads on pelican by experts in this field.

parts started to arrive........

Idle Jet
6 x 55,6 x 57
Main Jet
6 x 145, 6 x 162,6 x 165
Air Correction Jet
6 x 170,6 x 175

6 x Idle Mixture screws and springs
6 x Main Jet Holder
6 x air mixture control screws
2 x Needle Valve plug
2 x threaded plug (directly above idle mixture)

A new/old float was sourced from Tom Butler at Rennshop.
The new K&N Air Filter set from Henry Schmidt at Supertec Performance

Stuff started to arrive, and the cleaning was done, time to put this one back together.

but some careful thread tapping needed to be done first to plug various redundant holes!

Shane, thank you for your detailed and documented experience. I will be undertaking this project in the next few months, and this thread will be a great help. Can you share your source for the 34 mm Venturi, and also contact info for alfa1750 (I checked the eBay store, but couldn't find contact info)?

Thanks.

The new Venturi fit perfectly and are well made, I re-used the emulsion tubes but installed new Air Correction Jets. There is heaps of great technical advice to be found on pelican and after much reading decided to go with 57 Idle, 165 Mains and 175 Air Correction. Interestingly the Air Correction jets removed were 210, with other variants used in the original design, 185 and 195 depending on year from what I can work out.

The Pump Jets went in next with new O-rings, but you have to put the gasket on first!!! So they were removed and installed again later. I used a small dab or rubber grease on the o-ring for easy installation, and you need to make sure the gasket is orientated correctly.

I had installed the PreAtomisers with new clips, the sequence of pix here is not quite right because these should really go in before placing the gasket, which I obviously did, but the picture taking is a bit off, but you get the idea! I broke one of the original clips while doing this, so what followed was another long wait for new ones to arrive.
I found that you have to install the clip and atomiser together holding the clip in place while gently working the atomiser into place.

Hi Rodo!
From who you bought the venturies?

Thanks for this thread.
I'm working on mines also.

Great thread! Thank you!

It's obvious but I made sure the pre atomisers are orientated the correct way round with the fuel inlet opposite the emulsion tube and clip recess on the clip side, and the clip also right way round with the bulge face to the atomiser. I installed these together, not the atomiser and then the clip, but by inserting the clip half way and using the atomiser to hold it in place while pushing gently on the atomiser and pushing the clip at the same time.

I did the Idle jets, idle mixture screw and air bypass screws next. The new idle jets seem slightly longer (although photo does show that) than the old ones and none of the o-rings on the kit would fit. The largest o-ring in the kit is shown on the idle jet below, but it's too small. Enquiries on pelican about the use of the o-ring on the Idle Jets indicated these are not necessary as the jet rests firmly against the inlet. You can see the old o-ring and new Idle jet with no o-ring. I had new Idle mixture screws and springs and these too require an o-ring. The issue I have with the kits is there are no instructions or guidelines to indicate what o-ring goes where. For seasoned experts this does not prevent problems but for DIY's it would help if there was at least some basic guide. Via process of elimination i choose an appropriate sized o-ring for the idle mixture screw and installed it by mounting the screw in a vice, using 2 old mixture screws to get the o-ring in place. I guess a small compass would do the same trick.

Nice Carburetor Build! Good looking car too.

Just for added information on rebuild kits, Allstate Carburetor obviously sells the same kit as pelican for the 40 TIN Zenith, but for a little over $50. The reason I'm pretty sure it's the same kit is because I bought two from Allstate years ago and recently had a fuel leak between the manifold and carb. So I used the manifold gasket supplied in the kit, and it too was the wrong size from bolt to bolt. However, the intake hole is the correct size, so I gently knicked out a slight bit more of a hole with a paper hole punch toward the outside of the gasket on both sides of the gasket bolt holes, and then the gaskets fit fine and I have had no leaks since. The kit is not a perfect kit by any means, but at least I didn't spend $90+ on it. Not to be down on pelican by any means. Pelican is a great forum, and a good vendor, but like any Porsche parts vendor it's hit and miss for some parts. Pelican is just selling what they can get. At least now I know not to buy a kit from Pelican expecting a better product. So this write up has saved me money. Thanks again!

Thanks 924CarreraGTP, had a look at the AllState kits and they look identical and almost half the price, still half the bits I found I didn't use. There has to be alternatives. If I did this again I would try and source from alfa1750, but there must be others who supply.

These are some 40TIN carbs we just completed.

We have standardised a system to refurbish Zeniths where we hone each throat and increase diameter 0.25mm and fit a new Throttle Plate which we manufacture.

We also line hone the throttle shaft bores to 0.25mm oversize.

We have throttle shafts in both standard diameters and 0.25mm oversize, which are currently out of stock but we will have more in the near future.

We have modified the shafts with a cut away section to both improve air flow and to allow us to use the same throttle shaft screws on all of the other shafts we will be making. (Weber, Solex and MFI)

We have reduced the end section to 5mm diameter so we can also share the shaft coupler with the Weber carb and improve pricing for new couplers. We could make shafts without the reduction in section but I am not sure there is enough demand.

I would agree with comments about gasket quality in many of the repair kits - they don't fit well and the materials never look very good.

We have made our own gaskets using Klinger materials and they are a decent fit.

We are slowly working our way through a range of parts.

We have re-manufactured all of the springs for the Zenith, Weber and Solex 40Pl and will make the MFI springs in the near future.

We have Diaphragms in a Contiflex material that is Ethanol resistant.

We have gaskets for Zenith, Weber and Solex 40Pl all in Klinger materials.

We have insulators in an Epoxy Fibreglass Flame Retardant material.

We have the O Ring seals for all three carbs being made in Viton B and all of the fibre and copper sealing washers to the correct thickness but these aren't finished yet.

We have manufactured Zenith Venturies in 34 and 36mm diameter and will have 32mm in the near future, Weber venturies in 34 and 36mm and Solex 40PI in 32, 33 and 34mm.

We have just completed all of the hex nuts, studs and cheese head screws used on all of these carbs as many are missing or in poor condition and are not commonly available.

There are a variety of reduced hexagon M8 full and half nuts with either single or double chamfers most are 12mm AF but one is an 11mm AF and we have a full selection.

The cheese head screws used on the Solex and Zenith are an older style than the parts now being sold so we have re-manufactured these screws to the original pattern .

We have also made the M5 studs for the carb bodies and M8 Studs for inlet manifolds.

We have a few more parts to complete, such as drop links and then we will be able to supply most parts.

Good job,have nearly completed mine and found very little wear in spindles (thank goodness),I didn't remove my floats as the screws are easy to strip,didn't think it was a problem anyway .
What did you do for gaskets under the velocity stacks?,the kits don't have them.
alfa1750 kits fitted very well and have parts included thats others don't,service from HER was great also,she even found a replacement air bleed screw as mine had been broken by PO.
A word of warning for those thinking of doing these carbs,NEVER do up the spindle nuts without locking the throttle cam properly,I learnt the hard way and ended up with a spindle twisted out of line with the rest,took a bit of work to fix:confused: .
I found these carbs to be well engineered and pretty easy to do,forget all the BS about part supply as opposed to Webers,I was able to get all the parts I needed and looks like this poster had no issues.....its just the waiting thats a hassle;);).

I Have a question. Do all the jets have aluminum washers ? I removed the main jets on mine and they didn't have any. I check another pair of Zeniths and the same .

I didnt even notice a rubber o Ring

I only noticed the o'rings on the air mixture and the injection tubes

Never mind .... I figured it out :D
