ok, I figured it out!! A carb guy told me that the carbs were "specific" to application. And that small engines had different vacum requirement at idle than bigger engines had. And most of these carbs were on 283's and such. He told me to drill out the idle air passages about 5 thousands and it might work. But instead of that, i had scored an early olds tri power at the swap meet a few weeks ago, they needed rebuilt tho. I was thinking that early olds' were bigger cubic inches than 283's and closer to the 348 size. So I robbed the booster cluster from one of those carbs and put it in the rebuilt carb and........
It started right up and idled perfectly!!
Never would've guessed that one!! Just thought I'd share what the outcome was. I drove it to the KC Goodguys show and it done great all weekend.
Thanks for the help.
