One other thing that maybe affecting engine is that fir what ever reason theres a resistor plug on engine.Ive read that an engine that didnt have an R plug to begin with,the R plug will retard timing and spark is not as intense,in watchin a vid or recommended plug is ngk bp6es,nothing over here that will even cross with ut do itll be a coupla weeks before i get 1.Also just an fyi my engine didnt have any starter with it so i put a 7″ pulley on pto side,coulda made a ratchet starter but i like rope starts a bit more friendly especially if it back fires on startup.Orignial sediment bowl and plumbin was f’d up a bit from previous owner so had to put a fuel stop and filter.I will get a pic or two up soon.
