ok just got my second ss motor yesterday. started break in just idling 1 tank. that went great my 2nd tank it started flaming out. after going through 2 charges on my starter box new fuel line and a new tank i just cant keep it running. im using a re11( thats what the lhs told me to get) after a very pissed off day i realized that there was fuel in my air filter. and all day i noticed after it would idle for 10 seconds or so, when it would die it would spit back allot of air into the fuel line. please help
