2000 blaster borred one mm over. starts great but idles out after about a minute. if i give it throttle to keep it goin it bogs sounding like a sick 4 stroke then dies or picks back up to idle for a few more seconds then dies. my exhaust seems a little smokier than normal but not too much. checked my compression its at 120-122 psi. i have a few exhaust leaks due to it being old and abused. would that have any thing to do with it? just re-jetted my carb too. went from 200 to 190. (it was cutting out in high rpms. thats what the guy at the local shop said i should try.) the problem started after i took in some water. got it all dryed out tho. any ideas on how to fix this?
