With regards to the O.S. pumper engines, I have the original series O.S. 120 surpass with pump and c12 carb. this engine was recently involved in a dispute with the ground about 40 yards from the runway, and well, the plane lost the argument. But the engine survived, kind of. The needle broke off along with the threaded portion where it goes into the carb body, Believe it or not, this engine, pump included, ran like a dream with loads of power. I was wondering if you can point me in the right direction for a replacement carb that works with the 120 pumper? Or maybe a fix? I absolutely love the way this ran and this is the only issue after the crash, so any ideas would be much appreciated!
Have you tried Hobby Services that service the O.S. engines for a needle valve assembly? (2170398-0007. If they can’t help I’m sure Gary Conley, who now makes the Perry carburetors would have one that will fit. (630) 858-3199.
