Carburetor Question

Postby dfmonroe » Mon Jun 21, 2021 2:23 pm

I am reviving a 1952 Hummer. The carburetor on the engine is a L&L S-3, which I understand is from a later model 165cc. Can this carb work on the 125cc? Not knowing the differences would I rebuild with S-1 "guts" or S-3?

If the carb is a S3 and not just a S3 cap you have a 165 carb.
The 125 carb throttle piston is smaller.

I didn't frame the question well. Will the S-3 carb from a 165cc work well on a 125cc engine, or will I need to source a S-1 carb?

I do know that the S1 carb is smaller and the nozzle is also.
I would think it would flood a lot.
For the correct answer email Mutt under parts, he will tell you the problems if any.
