V4 vara not playing

[Riggers]

Ok so bike doesn't want to play was running fine ish when I got it but was really slow at pick up in 1st gear so changed the air filter as it was dirty took the carbs off to clean them as the previous owner didn't have them on right cables wct all over the place checked all jets all clear. Air mix screw set at 2 3/4 now it won't start without choke revs like poo and then dies when choke is released am I missing something ??

Check if fuel is flowing freely to carbs.
Follow Shop manual, Section 5 for carburetor service and adjustment.
