I think i figured it out. Left spark plug out over night. Kicked for a few minutes with throttle wide open. Then put the plug back in and fired right up.
Sounds like you cleaned it out and it fired right up!

Keihin carb with JD Jetting kit sea level setting. 36:1 ratio. Still hard to crank. When it runs for a little bit then dies and want crank again. New spark plug new air filter air screw 1.5 turns. I’m puzzled
