Hi Folks,
Can I please get some advice on adjusting the idle mixture on a Q-Jet? ;help
Keep in mind, I installed the Q-Jet last March, but have never tuned it properly - or even driven with it installed.
As I understand it, the idle mixture screws are located in the front base of the carb, and that you're supposed to adjust by 1/4 turns.
It may be just me, but I'm having a heck of a time accessing and adjusting these screws. Is there a special screwdriver or something? I spent a considerable amount of time trying to adjust yesterday. It was really difficult to see and turn the screws accurately, and I injured my hand by accidentally touching the fan! Talk about feeling foolish.
I was in the midst of tuning and mapping the adavance cruve per John Z's article. So now, I have a cut hand (yes, it could have been much worse), and the adjustment is totally off... the car would hardly turn off! It just kept dieseling. It finally coughed and died. :cry
