I need ideas. Will not run at all. New top end didn’t run before it sparks but maybe not super strong i don’t know. I’ve tried gas and I’ve tried ether. Freshly rebuilt carb gone through throughly. Wiring kinda sketchy but I see spark. Valve timing is good clearances seem good not an expert though. I’ve ruled out fuel because I’m using ether. No gas in oil. Kill switch is off. Please help I just want to ride it! I noticed if I roll the motor over in a specific spot back and forth the carb breathes in and out of a vent in the throat of it is this normal? If you want me to send a video of it let me know and I’ll send it where ever nesscary.
