Afternoon folks amd welcome to my nightmares. 02 wr250f. Kick only. Issue.
Will not idle, dies. Hard start. Legs hurt.
Previous owner jb welded the flywheel nut on. (Wire was broke on stator) it’s now fixed. Engine was out, stripped and crank was fixed at crank shop. Re assembled. Ultras sonic cleaned the carb. Won’t starts. Checked ohms. For pickup, stator all with spec. Take a car now off a 03 wr. Starts and runs, won’t idle. It’s at like 2500 slowly unscrew and dies. Runs long enough to check timing with timing light. And that within the fire range. Re installed my carb, kick like hell. Starts won’t I idle.
Change do the jet From 40 to 42. No difference.
Air filter was garage, was removed. No restrictions.
Valves were checked and within spec. New plug. New fuel.
Timing shows advancing when reving. So. Cdi is working.
Any gurus or ideas. Cheers,
Morgan
