Hello, I have a Holley 0-82751SA on a 327 with a 294 cam [email protected] on a 104 LSA. 26 degrees initial timing, 10 degrees mechanical, I didn’t have a chance to check how much the vacuum advance is pulling but I only have 5” of vacuum at idle. I’m using manifold vacuum for the vacuum advance. Stick shift car. I have a brand new 2.5 power valve installed. I had to open the secondaries a little so I wouldn’t have to open the primaries open so much at idle and pull fuel from the transition slot. It was open too much and there was vacuum from the ported port at idle which let me know I wasn’t on the idle circuit. I got that situation fixed but the thing is running EXTREMELY rich. So rich I don’t feel comfortable taking it anywhere because it loads up. It starts up cold with a higher idle and then once it runs for a few minutes it’ll go down because it’s just consuming so much fuel. I don’t have control over my mixture screws. The idle air restrictors are not removable and I heard about sticking some wire in there to restrict the amount of fuel but it makes more sense for me to try to change out my idle air bleeds to a larger size since they are removable at the top of the carb. I currently have 71’s and I was thinking about going to 75’s, do you think this will allow me to gain control of my mixture screws? Thanks.
