I have a B/S 12.5 hp vertical engine on a splitter. Model 219802, type 0117E1, code 05102ZA.
After head gasket replacement, engine runs fine but only if choke is about 1/3 on.
Opening choke on warm engine causes the engine to make a popping noise. Popping is random (it does not pop every time the engine fires) and happens every few seconds. I am thinking that it is running lean and maybe main jet is partially clogged. Any guidance would be appreciated.
Thanks,
Knots

did you reset the valve clearance after you put the headgasket on?

Also can be a bad or missing intake manifold gasket.
