I have a lighted magneto for a Tecumseh, i believe it came from a 1972 HS40 rupp roadster. Also have a Tecumseh allow flywheel #610769a. I have a freshly rebuilt HS50 engine from 1975 (so it has the same flywheel taper as the HS40), which I wanted to put on the lighted magneto and alloy flywheel
Seems easy enough right? Install a new condenser, and file the original points (don't like replacing points as new one never seem "right"), set the points to .020" gap, set the points timing to .035" btdc, and off we go right? but no, i can not get the engine to fire. It kind of tries, spits a bit, but that's about all i get.
So i put a stock magneto (non lighted) with new condenser, filed points set to .020", set timing to .035" btdc, and a #32517 alloy flywheel (non-lghted) on the motor. And it fires right up.
Maybe the lighted magneto is bad? I have a *second* lighted coil magneto, try that, and again, the engine will not fire.
So on a fluke, i install a different flywheel on the same lighted magneto. This flywheel is cast iron with all the magnets. Damn fires right up, and the lights work great.
So what's the deal with this #610769 flywheel? why won't it allow the motor to run??? I really wanted to use this flywheel, as it's lighter weight than the cast iron version, and it would allow me to put an old style rounded blower housing on the engine.
I put then engine with the cast flywheel on this Speedway Red Baron bike. it runs great. just wanted the alloy flywheel for better performance...
