Okay, I broke down and tried Ralph's method of checking the ignition timing, and it looks like it may have been a bit retarded from the 28 degrees it was supposed to be at. I'm going to reset it tonight to 28 degrees and see how it runs tomorrow. Just to double check, Ralph, if you're reading this, if I've found top dead center, gone CW (looking at the front of the engine) 28 degrees ( I think it worked out to be .366, and then loosen the timing ring and move it so it just fires, that should set the timing to 28 degrees BTDC, right?
Thanks
