what carb should i use for my 1988 mazda b2200?

That sounds like a cool trick to pass the visual inspection part of the emissions test with a weber carb on.

I've put a Dualjet [(Verajet) half a quadrajet] off a mid '80 GM v6 on my 93 2600. May have to make an adapter plate (do not know if landing is large enough to drill mounting holes on a 2200), manufacture a cable position bracket, use original cable.
