It’s a Sears engine and cross checks as a HS30 assuming the shroud hasn’t been swapped at some point...
Anyway, It will idle for the most part but unless the high speed jet is completely closed it stalls when I give it any throttle. With the H/S jet closed it will throttle up but runs poorly. Black smoke and I’m pretty sure it’s backfiring. I had it running without the air filter and saw gas spitting out the back of the carb.
I don’t have my compression tester but it pulls like it has plenty of compression. I have the ignition timing set as close to 0.035 BTDC as I can get it. I only messed with the timing because I had a suspicion that it had been messed with prior to my getting it. I haven’t checked valve clearances yet but they are closed at TDC. The carb I have on it is an old Tecumseh off of a HS40 that I cleaned up and I’m pretty sure is good. I’ve had plenty of dirty carbs not idle but never had one have a problem throttling up so I’m thinking I must have screwed something up setting the ignition timing.
thanks for any help you can offer...
