is there any way to increase the idle circuit on a holley 600cfm vacuum sec carb? i had to drill 1/8" holes in both primary throttle blades to get it to idle without dripping from the nozzles on my 455. it also would pull too much vaccume on the vaccume advance(about 10 inches out of 15 at idle)
BTW, i don't have money for a bigger carb or to send it out, so thats not an option.
thanks.
