    Has anyone ever used silicone on a carb base? I've heard its a no no. I thought of using 3M window adhesive(gorilla snot). My carb is a little pitted on the bottom and its contributing to my vacuum leaks. I was hoping I could seal it up a little tighter. Please lemme know what you think.

    I would say no. If it is pitted that bad try to find another one used and use the base off of that,assume you have a q-jet. Have seen these at swap mmets for around 20-30 dollars. Not sure if they all interchange though.

    Had a buddy suggest a thin film of grease, said it would fill in the pits and the rest would wipe away or get blown out the exhaust. I think he's about 100 years old and been around the block a few times so I don't think he'd steer me wrong on this. I'll let you know, thanks for the feedback.

    You can fill in the surface with JB Weld, before it sets up wipe the extra with a puddie knife. Then use a ulta flat b
    lock and sand paper to make level.
    Good luck
