Hey all...here is my problem, caused by me.
I have a Rochester Q-jet carb. Its on a 76 Corvette. Well I thought the fast idle was too high so I went to lower it. Turns out I was turning the choke pull off screw, not the fast idle screw.
I went out this morning to start it and it just turns over. The butterfly is closing all the way, then when I turn the key its opening about 1/4 inch, and I can smell fuel.
I do not know where to adjust the choke pull off screw for a good starting point, let alone back to where it was before I started to mess with it. I've tried all the way in, all the way out, in the middle and no start still. It keeps turning over, thats it.
I had ZERO problems before I screwed around with the carb...what a d/a I am, lol. No problems other than the perceived high fast idle, which was about 1300 rpms when cold, then to 700 when warm. I've been told that 1300 for a fast idle isn't too bad actually and it did kick down as it was supposed to.
Thanks in advance.
