PW50 won't run or runs poorly(carb is cu-lean!)

[nick novice]

Dudes,
I'm baffled! I've been riding and maintaining my cycles for 28 years and I've had more weird problems with these lil' pdubs than anything. Do they have a history of magneto or other electrical problems? I ask I've already replaced a magneto in one. This one has the same symptoms. It has spark. But I'm not sure it's as strong as it should be. I had swapped carbs, cdi, and coil with the runner and still nothing. Well it starts sometimes but runs like butt. I threw in a new plug. I was told i could tighten the gap a little and that might work if i was having a weak spark. Not any better. Any thoughts?

Make sure the exhaust is not plugged up. I have worked on many of these small two stokes that will not start or run right because the pipe is almost completely plugged with carbon

Thanks. but it's clean. i recently restored this thing top to bottom. it's pretty fresh. minus the problem i'm having of course...

The whole kill switch setup is a PITA on the pw's. Try a switch off of a different unit, or it may have moisture. Flush with some wd-40 and let dry... :nod:

Switch to a TTR! Will solve all the problems.
