i recently picked up a 96 blaster. the previous owner had the top end rebuilt. didnt get a key so i disconnected the ignition. got it started for a sec. then it died. noticed the head wasnt torqued so i replased the gasket. i could get it started but not very easly. had to really mess w the throttle to keep it alive. but it would just bog down and die after a second or 2. figured it was the carb. rebuilt that still nothing. so it had a 220 main. and a k&n air filter, w no lid. i figured w only a 220 i would go bigger. i bought a few different sizes. started w 290. but but w the rear part of the air breather off the gas would shoot out there so bad. and still had to really mess w it to get running. and it wont stay running,bog down& out. hmmm. figured i'd adjust the needle. went from the 2nd to from the top to 2nd from the bottom. also took the main down to 270. still took for ever to get started. when i finally did i took off and it died 100ft or so and still shooting alot of gas out the back of the carb. so hard to start and not sure how to set up carb! also the carb lid is just about stripped out. air leak?
