haven't been on for a couple of years but could sure use some help. Got a nearly new Dingo 250 las fall (2007 model) and after I got it running, it won,t run or start when warmed. Been thru 3 started relays and its time to get to the root of the starter problem. Runs great when cold. Can't find the a/f screw and I think it has an electric choke. Any help will be greatly appreciated.
