Re: Elgin 2hp Model # 571 58211
Without me taking time to look up the number, let's just say that if it has fins on the powerhead like a motorcycle or lawnmower, it is air cooled, made by West Bend, later known as Chrylser, then Force. No fins, then it is water cooled and has a pump.
That West Bend/whatever air cooled motor is one of the few that is worth a durn. Unlike most it does not have a water pump to cool the exhaust. Instead, there is a small tube sticking out the exhaust outlet and curving forward. Prop wash forces water up through that tube which spills out at it's upper end to cool the exhaust. A trouble free system.
