Ok. I "thought" I read somewhere on here that it's a good idea to use this stuff to seal the carb bowls. I was at the auto parts store the other day and the kid gave me a tube of the stuff that "should work". So i just finished putting this sticky **** on and I noticed on the back of the tube that it says not recommended for parts near gasoline. In your opinion should I strip this stuff off? or am I ok?

Thanks.

Here's the stuff...

I would take it off. If it's not compatible with fuel then it'll turn to mush and probably plug something up.

No idea what it was, but I've been running this red liquid gasket stuff on my Vespa carburetor bowl since 1998. Came in a tiny tube and I had to let it dry overnight. So far, it's doing the work of a black rubber gasket that I obviously didn't have back then.

So I know they make stuff that will do what you're looking for. For the 350 carbs, I'd try to find the same thickness black o-ring material and cut it to length and apply a dab of RTV at the point where the two ends meet. Should seal up fine. If your float height and float valve are functioning correctly it shouldn't put a lot of fuel at the seal anyway.

I just sealed up my bowls with Permatex Hylomar and a Cork/rubber home made gasket. The Hylomar took the place of the float bowl rings that I do not have. Care must be taken not to let it glob up into the bowl and get on the float. It makes for a quick test of the overflow tube. :lol:
