Just bought an '00 Blaster yesterday. The guy said it is bored .30 over and it has a FMF Gold Fatty. Air filter is off, its missing a bolt on the intake and the 2 side cover for the throtle mechanism on top of the carb. So what he told me is: Hes messed with the carb and he isnt a carb guy at all. Hes messed with it for weeks now and so fed up he sold it to me for 550. Thing is in good shape, good compresion but with the seat on it it stalls. Wont idle. I dont know if the jets need to be changed for the pipe or what. I havent broke open the carb yet. He said he has the needle set at 5 down which is obviously saying there is a carb problem. It starts preety easy. Like i said ive had it for a day and its at my uncles for him to tear into the carb etc. Are there any other ideas on what the problem could be? Thank yall
