help with carbs please

heres what im working with...it sat for a couple years before i bought it- so first i steamed out the tank and tore apart the carbs and replaced the filter. they had a lot of varnish and i actually had to clean them for the 3rd time now...rookie mistakes. (im a diesel tech and drive an integra...so carbs and bikes arent exactly my strong point, but i can work my around just about anything with some good advice)

what the bike is doing is its impossible to start without using either(c-mon start you bastard) once it starts it will only stay runnning at about 1800 and higher rpm(im guessing because i have no tach), ive tried adjusting the idle cable to its min and max and nothings changed, it wont stay running unless holding the grip. i was doubting the fuel pump was working properly so i bypassed it for now-but it didnt seem to make any difference.

now things i "think" i need to try-if you can tell me which to try first or which arent necessary. float adjustment-i dont have the tool to check fuel level in the bowl but its my first guess(i was very careful not to bend the tabs and the seat's seals are in good condition)

next i looked at the butterflys and they may have been synced wrong-but im not sure...if the previous owner had them adjusted wrong could this cause my problem?

next which is the easiest for me to try because i dont need any specialty tools-is the pilot screw adjustment or dirt in it- would this need to be removed to be cleaned or should i even bother messing with it?

when i was cleaning the carbs, i havnt actually soaked the entire carb in chem tool, only removable parts-i sprayed out the passages with the spray, is this good enough?

are any of these things even close or can you give me some suggestions for refreshing the carbs? much appreciated!

thanks in advance
