Hey guys happy to be a new member, i have what i think to be a auto choke problem, never starts cold with out starter fluid, i have a new plug, carb cleaned by sonic cleaning and a new jet but still doesnt start, the only way i can start it with out starting fluid is to hold my hand over the intake but still starts and doesnt stay running i dont know what to do. im thinking it has to be the auto choke/choke but what do you guys think? thanks
