Carb ?



carb right




carb left


Every time I think I have it nailed down, I something a little different about this Motorcraft carb. I am 90% sure it is a 2150 because it has the variable high speed vacuum ports. I believe 2100 carbs do not.

I'm trying like hell to tune my truck to idle without having to lean on the power valve. I have opened the idle mixture screws from 1 to 4 turns and 2.5 seems to be the sweet spot.

Pretty sure I read on here that auto choke did not come out till 1968. So this is for sure not the original carb... correct?
