i've never had any luck with reman carbs from parts stores.... i've pulled them apart and found that the jets are different sizes, parts are missing, parts are installed wrong, and my favorite, they're missing a screw so they just JB weld it together.... in the shop its gotten to a point that i just make customers buy brand new carbs or get the one they have rebuilt... which i send it out to FSP they swap out a rebuild of the exact same carb or updated model of the carb.... and i've never had one come back with problems
