Oil in carb and on spark plug.....

[Rider-trx_250ex]

Ok so my 250ex has a bit of oil in the carb and oil on the spark plug.....i think it is the reason when I crack the throttle the quad stalls. But what could be wrong with it that there is oil in the carb and on the spark plug? Any help would be appreciated.

maybe the oil gumed up a jet ,take apart your carb and clean them and the inside of your carb, use carb cleaner and then spray it out with some compressed air, u can use a wire off of a wire brissel brush to clean the holes in your jets, use a pair of pliers to pull a wire off th brush,then run it thru the jets with your fingers.
