Good riddance 2025. HAPPY NEW YEAR !

Happy New year!

I can't help on the timing of the engine since I have never worked on one of those.. you'd have to go by the manual. .The piston would be TDC twice in each cycle. once on compression ( all valves closed) and TDC exhaust (exhaust valves open). But The timing marks shouldn't be lined up then.. The only thing might be if you are mistaking something for a timing mark rather than using the actual one.. . The firing in that video didn't sound at all like a firing under compression to me.. That is what I was going by.. To me it sounded just like some residual gas left in the cylinder after the exhaust stroke being ignited which would give the piston a bit of a push, but not enough to really spin it over.. Hopefully one of the other s has experience with that motor and can help.. At 82, I'm not that great at making diagnoses and interpreting what I see in a picture of the timing marks to what I would see if I was actually there with a motor open. With compression and ignition , I can only see fuel and timing being the missing element to it actually running and producing power. . Giving a shot of fuel directly into the carb should make it fire at least a couple of times with force To me , that only leaves timing as the culprit. Do you have a riding buddy that might be able to look at the motor with you and maybe spot something missed? That was how my error was solved on a car motor way back when.

Wow the National Mall with the Washington Monument lit up like a candle ....Happy New year
