I have a Holley 4160 vacuum secondary double pumper on my 302 in my '70. It's an 89 roller motor with a Weiand Stealth and Duraspark ignition. This project is always second fiddle to other things I've got going, so it's been taking me a LONG time to finish.
Anyway, the carb wants to idle at 2,000-2,500 rpm. I have a Holley carb manual, and I've removed it and done the adjustments in the book. Should I be looking for a vacuum leak? I replaced all the vacuum hoses when I did the swap, so I don't have old, cracked stuff in there.
Any other thoughts of what I should start with? I'm also wondering if there isn't something wrong with the linkage. I've noticed that the curb idle screw doesn't even touch the linkage. There's a little slack in the throttle cable, so it isn't being held open.
Could a poorly adjusted choke do this?
