I have a nearly new OS 46AX engine, maybe a gallon of fuel through it.
Ever since I bought it I have had problems with it. Dead sticks, runs
bad, dies if I let it idle for over a minute or two.
It is very strong engine and when flying it will pull my Hanger 9 Arrow
straight up almost out of sight. I have tried to adjust it by the
owners manual and almost get it set, but still has the 'dies at idle
after a couple minutes' problem. It also doesn't seem to stay set. What
I have noticed is the carburetor rotor (the cylinder in the carb that
turns for speed control) has some play in it. I know a little play is
normal, but I would say this is about 1/16 of an inch. If the engine is
at idle and I push in on the rotor the engine speed changes. It is
almost as if the rotor guide screw may be too small and allowing too
much play. Has anyone heard of this or have any other suggestions that
may help this motor that has had problems since the first run?
