OK guys, I've been flying for a while now, but this is my first endeavor into gas engines. up until now, I've been flying glow. The guy that I bought the plane off of (it's a 90 inch PT-19, kit unknown right now) was selling it for a friend, so he doesn't know what kind of engine it is. Unfortunately, the friend has passed away, and it's his son's that are getting rid of the plane. So, maybe you guys can help me identify the engine. My buddy said he thought maybe a US engines 42, but wasn't sure. He was pretty sure it was a 42 CC, but that was all he was sure about. The engine is made in the US, it is stamped on the top fo the crankcase. On the carb is stamped Walbro. that may be the brand of carb, I really don't know. Right now I'm going through the plane (as it's been in storage for a couple of years now) and fixing hanger rash and so on, and then I'll get with the guy and learn the ropes of the gas engine and the plane itself. Also, I have one more question. I know about electronic ignition Vs. magneto and so on. This engine seems to have a magneto on it, but the "magnet" has wires that lead back to the fuse, and tie into some odd looking thing that is hooked to a switch. The switch has what looks like a round charge jack on it (like on a transmitter). but, there is no battery. Is this an electronic ignition? If so, what size (V and Mah) battery do I need to get for it? The switch seems to be a three way switch.
Thanks for the help guys!
Here is a couple pics of the motor:
