Hello I have a 1986 250WR? I think.... It ran fine, started first kick everytime. I rode it for about 2 miles parked it, the engine died on its own as soon as i parked it, I was the told that the carb idle was set low to die on its own because the kill switch was unplugged (NO IDEA WHY). anyways it won't start now. It does get spark, sounds like it has compression, and is getting gas. Here are some pictures to give you an idea, what i have. ALSO kinda wierd, but it seems to have leaked a black oil from the exhaust for a couple days after It stopped starting..... The guy that sold it to me had a 20:1 ratio to make sure it was getting enough oil. I checked the raditator for fluid and say coolant in it, but If i feel the lines, there is nothing. Maybe it over heated? It has a BRAND new spark plug.
This next picture is off the inside of the cover that makes spark , or whatever. very dirty, I rubbed my finger threw the dirt:
