Hey guys,
I have some questions on where these carb hoses attach to on my Weber 38..
Previous owner capped one and the other two are just open. Also, I don’t have a charcoal canister and don’t need to pass a smog test. I’m ok with a deleted charcoal can. Top line is capped. Where does my front one run too and my back one?
Those are just manifold vacuum ports causing a leak. You can just cap them unless the Weber needs manifold vacuum. I have never set up a Weber, but I have messed with the factory carbs quite a bit. On a factory 22r, one of those ports is for the HAI, which is probably gone now, and the other one I believe goes to the charcoal canister. Depending on how much smog equipment is gone, the only things you need vacuum for is the vacuum advance, which uses two different ported vacuum connections, and the brake booster.

Thanks, so I guess I’ll just cap these two. I have a vacuum advance hooked up to my distributor. I did see some fuel come out when I poured fuel into the carb. That’s why I made this post. Thanks for the input
