i got a 2000 trail blazer,i changed the jet from 140 to 130 main.
still haveing the same problem i had with the 140.i go to full throttle it & it just bogs down.i also notice that when i go to put in gear it makes a loud grinding noise.any help would be appreciated.
thanks

 

I have a 99 and a 00 Trailblazer.I have not noticed any
problems with them bogging at full throttle. Is your pre-
filter and air filter clean? About the grinding noise.
Are you letting the engine RPMs whined down before you
shift into gear?

 

Talonhawk is right you have to wait for your engine to go down to low RPM'S before you can put it into gear.

 

My trail boss did that,look for the idleing screw on the sisde of da carb and trun it about a quarter of a turn to the left,itl fix it
