my uncle has a 1987 arctic cat 340 jag and the fuel pump went bad he replaced it (2 years later) and it fires right up and idles great but as soon as you hit the gas it bogs out let off and it goes back to idling fine. you can feather it up to get the track spinning like 20 mph and thats it and no matter what rpm you have it running hitting the gas bogs it down. the carb has been taken apart and cleaned well and didnt help at all. anyone have any ideas????
thanks in advance
