Newb......but i have to "full throttle" my trailblazer to get it goin. Otherwise, it will sputter all the way up to full throttle. It doesnt seem to affect the performance at full throttle( I can do and eat donuts all day ) but low to mid just sputters.

 

have you cleaned the carb? maybe the pilot jet is plugged. this jet controls throttle from idle to say at least 1/3 throttle.

 

Thank you, I'll try that.
