my 125cc 4 stroke dirt bike engine starts then dies after about 10secs when idleing . if you rev it up it immediately cuts out. i have checked jet valves they're all clean,float bowl {no dirt} and it is getting fuel .The spark plug lights up good aswell. what is the prob? its bugging me:(. would appreciate help.;)

I know you've checked but it still sounds like fuel starvation

Agree with Nodster, sounds like fuel-starvation, had the same problem with mine.

possible blocked up fuel tap on the tank, you'd be surprised the amount of gunge that gets caught in the gauze, also no kinks in the petrol tubing, air lock in the tank cap
