i bought a 2001 yamaha blaster for 350 bucks. i did not have spark when i bought it. so i fixed that problem. put some gas in it and started it up. when it got started up when u hit the throttle it boggs right down. so i took the carb off and cleaned it and tried it again. and it did the same thing. when u frist start it up it has good throttle response but when it warms up it starts to bogg down. so i need some help from here what can i do to get so it does not bogg down.
