Staton is old school and I think he's scared of a warranty on those motors, he probably had a nightmare of 75% of those motors being returned. Considering the cost of real Mits 43 or a tanaka if I were looking for a 40cc+ smoker I'd take a chance for $99. I have faith he's done his homework and the motors would be ok. Notice he says use no gas with ethanol? Where would one buy gas with no ethanol? I haven't seen a gas pump with pure gas in decades.
