is the air screw and idle screw the same on a blaster. i just rejetted becasue of delta vforce2 and ow it bogs in low to mid power. you can get a little throttle response right when you first get on the gas but right after that it bogs down and then stops when you get in to top end power i was readin the manual and concluded that either i can raise the neddle or mess with the air screww, but if it is the same thing as the idle i dont see how is could affect 1/4 throttle response please reply

 

Most Mikunis that I'm familiar with have only a pilot screw, which is not an air screw. Also they have an idle adjustment which is separate from the other two. The pilot screw is located on the underside of the carb at the front of the carb. The idle adjustment is normally a finger operated
****, usually on the rider's side of the carb. Turning it in raises the rpms..turning it out lowers the idle speed. I has nothing to do with fuel/air mix. If your problem is between 1/4 to 3/4 throttle, you may be a little lean in the needle jet circuit. Raise the needle to the 4th position (from the top). The pilot screw is merely a fine tune of the pilot jet which controls idle to 1/4 throttle. Two turns out from a gently seated stop should be about right.
Oh, BTW, on my suggestion on needle adjustment, I was assuming the needle was in the normal 3rd position, which is stock. If you've lowered it for some reason, then just return it to the 3rd position

 

the blasters idle screw is, if you take off the seat and flip up the rubber flap by the snorkel, it is under that kind of tucked away on the top of the carb. the air screw is on the left side of the carb in the middle, not the one on the bottom. The air screw will affect the throttle response.

 

Daredevil1,
Thanks for clearing up the air screw/ pilot screw location. On Warriors, at least, there is no air screw, only a pilot screw. In any case his problem does not seem to be with idle or even just off idle, so I believe the jet needle circuit is where he needs to go.
