I have pulled the tank, dumped it, cleaned the carbs as far as I can tell the tors has been removed I fire the sled up idles good I can rev it up to 3500 sounds great. if I try to go past though it just wants to die like turn in off the key also seems to want to die if I just open the throttle wide open! Bought it in November 13 it was freshly rebuilt it ran great but every now and then it would want to bog out and it would be tough to keep going for a few then it would take off again and be fine now I can't get it to move! Any help very appreciated and turning the choke on does nt help don't think its crank seals!
