Same ignition module for all those A&M engines. I went through 3 of the 3.2 engines in the early 90's. They all had bad cranks/bearings. They would go 8-10 hours before they went out, all while running the factory recommended oil mix. A friend had one and we put in my plane to test it. It went out in about 2 hours as I remember. I finally got A&M to trade me up to their new design 4.2 after the last blow-up. I only bench ran this engine, and got out of RC about '93 until about 2 years ago. Guess I'll put this engine in a plane one of these days.

Anyone know how this A&M 4.2 engine turned out? (This one has the crank as found in a glow engine)
