For starters you need to find out what size idle and main fuel jets, air correctors, and venturis you have in there. Do you have a pressure regulator installed? And an aftermarket fuel pump? I've got the same carb installed on one of my FB's so I know a pretty good bit about them. The Sterling I just won is for another FB project.

well i got it running pretty decent right now.. after doing some online reading.. the idle jets might be too small for the fact of how far i had to turn the mix screws out to get it to idle.. i have an aftermarket pump(cheapy mr. gasket till i buy another good one) a mr gasket FPR set at 4...my timing is 24L 16T at full spark advance. and its pretty accurate since i have a timing light that has a setting for 2 cycle and the digital spark advance.. ill pull it apart as soon as i can to see what i have in there or email who i got it from. it was bought brand new from racing beat about 5 yrs ago but i dont know if he changed anything inside.. im just happy its running pretty good right now.. runs like hell after 4k rpm.. get a bit of popping during deceleration but that can be i need a new exhaust.. any more input would be great
