thank you

I got my kits from a local supplier. I believe they order from SSF in Calif.

Rebuilding a pair of Weber 40 IDA 3Cs with a Redline kit purchased from Pelican. The main gaskets do not fit. I tried coaxing, stretching a bit. The gasket tore around two of the eight bolts and two of holes were still not on the bolts. This was on the first kit. I took out the gasket from the second kit just to see if it was any better. Identical. Laid them over the one that I took off carb and it confirmed. The holes are off enough to confirm the poor fit. I don't like the idea of soaking them just to get them on. I'll call Pelican on Monday. But I'm just wondering if anyone has any more recent information on a good source for the right gasket? I could cut my own, but that sounds like more work that I want to do. And I'm not comfortable using the one I took off.

Thanks for the link Henry. I don't see any rebuild kits or gaskets on the website. Are those sold only through dealers?

911 Vintage Parts can probably source them through PMO for you if Richard is nor so inclined.

Rebuilt the 40IDF carbs on my VW motor with Redline gaskets. They fit well when installed, but after a year or two they had shrunk into the air horns.
Maybe soaking in WD40 would be a good idea to keep them from drying out.

We make Weber, Zenith and Solex gaskets from Klinger materials.

We use Klingersil C4400 for fuel resistant gaskets and Klingerstatite for all of the 'air' side gaskets.

We have diaphragms made from an Ethanol resistant Contiflex material and we are just completing the O rings and 'thin' copper sealing washers.

We have made thermal insulators that fit between carbs and manifolds with suitable studs.



We have the correct hardware in terms of the relevant reduced AF Nuts for all of the carbs and the correct studs for the carb bodies.

We also have the correct metric nylocs with a 'white' insert and Cheese head screws that watch the profile of those used on Solex and Zenith Carbs

My local shop (which I like to support) likes the Redline kits because of the accelerator pump gaskets (which were a good fit). So I took their advice and had them order me two rebuild kits.

The paper carb top gaskets were terrible...just terrible. I called and spoke to some tech guy at Redline who claimed to have never heard of the problem. I asked about soaking the gasket and he suggested against it. Guy was pretty much an idiot. Told me to remove all the studs from the base and then use an awl to stretch the gasket while reinstalling the studs. Stretch a gasket while holding it down with two hands while I use my third hand with an awl to open the holes wider and then using my forth hand to reinstall the studs one at a time??? Sure...get right on it.

I am going to use a good old ring-binder paper hole punch to "oval the holes on both ends of the gasket. Holes in the center of the gasket look to be workable. Stretching the gasket will likely rip it...hole punch will put the holes where the studs want them...and most likely allow me to remove the gaskets without tearing them in the future.

In the meantime I am rubbing "rapid-grow" fertilizer daily on my shoulders to get those other two arms to grow...

I'd suggest spraying the PMO gaskets with a gasket sealant/dressing spray because i've seen a number of PMO carbs with unfortunate weeping leakage from the top covers. The fuel leakage runs down the carb body and stains it brown. Dressing the gasket is easy insurance to reduce the weeping thru the gaskets.

Most of the 'fibre' gaskets still being used are made with an NBR Binder and these materials suffer as the quanity if Ethanol added to modern gas increases.

We have just started trials of top cover gaskets using a Klinger Top Chem 2000 materila which uses a PTFE binder that should be competely resistant Ehtanol which we belive is the cause of the 'brown' coloured leakage that seems increasingly common.

The worst example of this which we have seen is on a car the lives in France and used E85 fuel..

We believe that these gaskets may solve the problem and we fitted them to the 'French' car about 3 weeks ago and will monitor the results.
