weber rebuiding guru

i purchased an old set of webers on ebay for my 2.7l.


i want to get them rebuilt, who is the best person(s) to do this in australia?

You can do them yourself Matty.

Order a pair of rebuild kits (one for each side). Disassemble and rebuild one at a time using the other as a reference. They are very simple, just lay it all out in ordr on some corrugated cardboard so nothing rolls off your bench. Buy about 5 cans of carb cleaner and have access to compressed air (if you can).

Things to watch out for - holes in the floats, play in the shrottle shafts, the 14mm caps over the needle valves can be a complete bastard - be prepared to cut and destroy them to get them off and go with the later 17mm caps. Don't disassemble the shaft rods (if there is scoring in the throats where the butterflies are or play in the shafts, then they will need to be sent away)

I've got quite a few resources on rebuilding these carbies off the net. Wayne's 101 book is excellent and covers this job.

I spent a couple of hundred and bought the weber/zenith float gauge for setting floats and a synchrometer. These are essential and you will always appreciate having them. Where are you - I may consider loaning them to you.

This is a great project and will give you the confidence to take on other things.

Fishcop thanks for the advice mate, I have rebuilt carbys before just not these if there is play in the throttle sharft ho is Australia can fix them?

i think this is a pretty bread and butter job for most porsche shops

change the venturies to the long (906) style while you're there too - PMO sells them (along with jets etc)

I'm sure there is... "Eurometrix" or similar rings a bell, there would be a few. Try a google search in Aus for weber+service or something similar.

Along Ryan's advice... I've been searching for the tall secondary venturies, and can't seem to source them. Last fax to PMO said they were out of them also. Your current main venturies will be 27mm, you need 34mm. I had mine machined out from 27 to 34 after borrowing a genuine 34 for a the machinist to copy the profile. Depending on your set-up, I have some jet/air corrector sizes for you to try (I got them of PMO who are recognised as gurus). My car pulls strong all the way.

PS They are super float-level sensitive, it is essential that you get the float levels perfect or everything else will be ****. If you're in Brisbane, I'm more than happy to give you a hand.

Matt I am not sure where you live but Ian Stewart from Carb Tech in Redcliff will do a excellent job.

He worked for Weber for many years and worked on writting the Haynes manual.

He is also a handy Rally Navigator having spent many years with Ed Ordinsky.

I'm in sydney I can send them up to him if he's in Bris.

He sounds likea bit of a legend
