OK, a couple of more questions. From looking at the pictures above, is this a magneto engine, or EI? I can shoot more pics if you need them. If it's magneto, what is the black box that the wires go to, and the switch and charging jack? After looking it over last night, I couldn't tell where a battery would hook up to the system--it's just the switch, "charge jack" and some wires that go to the engine. Also, the plane has a 12 OZ fuel tank. How long will the engine run with 12 OZ of fuel?--considering an average of 3/4 throttle.
One more question--what was the oil mixture for US engines? I can't find any information about them.
thanks.
