A fellow RC pilot and kind soul gave this to me in 2016. It has been converted from its original magneto ignition to a CH electronic ignition by Ralph Cunningham, which is a mark of distinction. I have been in touch with Ralph and he let me know that he started this type of conversion around 1989. He provides a lifetime guarantee, and it's still valid on this engine.
This engine is different from my other gassers in several respects.
Mounting - There are three mounting holes and they have 10-32 threads.
Carb - It's a Walbro WA197A with no choke.
The carb is also reedless.
Ignition connection - RCA jack vs JR/Futaba connector.
Muffler - points in an interesting direction.
Because so much about this engine is new to me, I'm building an engine test stand to try it out before I put it on a plane.
