I have a 600 cfm Holley 4160 PN 0-80457 on my 302 in my 70. It's a 302 from a 89 Mustang GT with a Weiand Stealth intake, Fox factory shorties and 2.5" dual exhaust.
I have a couple problems with the carb, but I no longer trust the advice in my Haynes Holley Carb Manual after trying to use it for the basic set up and getting the car running. Uggh, sorry for the long post.
The car is running very rich. I get black soot out of the tailpipes on startup, so I assume that is the problem. I think I need to jet the carb down. Any advice on what jet(s) I should buy/start with?
Also, the choke makes the rpms race too high and I think it takes a little too long for the choke to come off.
What order should I tackle these problems? Is one adjustment likely to affect the other?
