I'm with ya, bud!
Thing is, I'm not so sure the carb I presently have is correct itself...power seems a bit anemic, likes a touch of choke, doesnt idle well.
Just got an email back from Holley. I had asked about the specified carburetor fitting 3 very different engines and about jetting. They responded that their carb would be correct if I ordered for my application.
I told them carburetors are NOT like tube socks, one size does not fit all.
