Loncin engines

Yet another problem, I was working on a Craftsman snow blower with what I think in a Loncin engine. The carb was 100% bad so I bought a new one on line, installed and started right up. Now when you shut off the choke in starts to surge, put choke on a little it stops. I have tried where you drill out the very small orifice but that din't help at all. I even tried another brand new carb, same issue. Any ides? Thanks you

Yes you can drill out the main jet but don't go too much or it will run lousy. Search YouTube for "engine hunting and surging", many show how to drill out the jet, especially Bruce Pender, Taryl Fixes All, and Donyboy73 vids.


Also the Idle Air bleed hole may be small, Check out Steve's Small Engine Saloon's video on enlarging the idle air bleed hole:
