NO, the original plug doesn't light. I have a couple others, but I don't know if they are 2 or 4 stroke. I have been trying to start it now and it really seems to me there is no fuel getting in there. I just cant see it well enough. If I take the fuel line off and plug the muffler and turn the prop, every rotation a little fuel squirts through, but when I put it back on the engine, I just cant see if any is going through or not. The plug is lit up very bright, throttle is open, carb was cleaned out....how do you generate the suction to get fuel in there. Because the carb is on the bottom of the plane, I cant plug the intake valve...its inside the fuselage. The plug that's in there is the one that started it for a few seconds last night. I don't know how to tell difference with plugs.
