Amigos,

I am at a loss: my carburetor is simply shot. I guess it's simple fatigue on a 60 year part that has been taken apart too many times by inexperienced people. We've adjusted the floater as much as possible without risking breaking something and it is still overfilling.

I cannot seem to find an SD40 in good condition to replace mine so I am now thinking the unthinkable, sinful idea if installing a Weber 32/36 from TPI...
...OR getting an old Chevy carb in Mexico that is in good working conditions that fit the 1F single barrel manifold.

I am at wits end with this problem and don't know what else to do...

Does anyone have experience with the Weber 32/36 carb? I know OEM is better but my resources are scarce in Mexico and sometimes one simply has to be practical.

Cheers!

I have a Rochester 2 bbl that came on my 72 when I got it in 82. I had to fix the accelerator pump leather gasket back in like 2000, that bonded to the wall with like a clump of glue. Other than that I have never had to do anything to it, other than some carb spray every few years. I bought a heated ultra sonic cleaner and a gallon of carb juice to really clean it out after all this time.

The float controls the needle valve which shuts off fuel flow when it seats. The needle valve can be easily damaged due to modern fuel or impact damage, poor mechanics. The seat could be damage or there is crap in the way. Too much fuel pressure will push fuel past a good valve. Clean and inspect the parts. There are vids for carb work from a guy here - I don't recall his name right now.

I can't thank you enough for such a detailed response as well as the resources shared.

I will give the carburetor one last go.

Thank you again!
