Carb has too much idle hole drilled?
Hey folks, I just got a hold of a 0-80540-1 holley double pumper 600 cfm carb with the 4 corner idle. It was an ebay item but it is so clean, you could eat off it. Only problem is...
It came with the butterflies drilled, I assume for a wild cam of some sort. The thing is, I cant get it to idle any more than a really lopey 500 rpms or a shaking the car 1200 with the pedal in. Is this way too much for a stock cam or should I be able to compensate with idle screws? The A/F guage reads full rich but it is never accurate anyway.. I DID fog the cylinders (Pour oil in them) after removing the heads and scraping the carbon off the stock pistons. How much should that interfere?
