my blaster has a weird bog to it at first i could only go 1/4 of a throttle then past that it would bog and stall then i took my air lid off and it ran good and i cleaned my air filter and put the lid back on and it did the same thing couldnt go past 1/4 throttle so i took my air lid off again and it took off then belive it or not i pulled my carb off and took the float bowl off and my main jet was not screwed in?! i know it was when i put it in so i put it back in and now it just boggs randomly but if i run it with the throttle pinned it runs fine anynody have any suggestions?
