Hey guys. Runs with choke at setting 1 and 2, but choke full off it dies out. New carb, spark plug, good fuel, new fuel filter/air filter.

I do notice leaking at head and it appears that it’s letting fuel back out the choke port into air filter then hitting the exhaust and smoking. Any ideas?

Engine not loose. Just had it all apart and snugged everything up. I’ll try the carb adjustments. Thank you!

If this is the TB320BV, it will have at least one mixture adjustment screw (sometimes two, but not always.) You will need a "Pac Man" adjustment screwdriver to adjust the screw(s) properly.

Also, on disassembly, I’m questioning my gasket placement. Do these look correct?
