Hi Guys,
Today my trusty 1999 300 king quad stopped on me!!! Its such a good bike. I have checked the fuel and it seems ok? eg its getting fuel. I have also checked that there is spark and there is, so i was after a bit of advise where to look next as I have never had a problem with the bike and there might be simple fix for it that someone knows about.

Any help would be greatly appreciated.
Cheers Jock
