if a trailblazer is tuned near perfect it will run unbelievable...i no mine is near perfect on top and a lil lean on the bottom and a lil rich in the mid. mine gets stronger as it gets hotter on bottom, the mid loses a lil but on top its always running good.

and 1.5 turns out is the stock for the airscrew and the farther out th ehotter it will run

 

ok i just need to know exacly where this air screw is located on the carb and what it looks like. I just dont want to adjust the wrong thing. TBsleeper, how did you get your trailblazer tuned like that?

 

mine ran strong at all throttle postitions and at all temperatures when it was stock and modded.

 

jsut kept playing with teh jetting and still am!!! gotta fix that low end and i almost got it fixed and the mid im not the worried bout cuz i rather it run rich there cuz i ride alot in mid

 

by low end do you mean at idle so you need a different pilot or is it the needle?

 

yeah im going to see if that air screw was my problem, and if not, i dont know what im going to do

 

i did change the pilot to a 30 and i lost te stock one so idk wat it was stock
