Office of Steam Forum for Model & Toy Steam Gas & Hot Air Engines

I found also if I don’t keep a fan keeping the side of the engine that has the hall sensor it will start missing and quit. I have more of Jin’s engines so I switched ignition modules and hall sensors and the same results. I don’t have that problem with my Knucklehead. Seems this engine heats the sensor more. With the fan blowing on that side it keeps running. Another flaw.

I hope Jim can help. Keep me posted.
