Honda running rough? any help please

Hi guys, i need some serious advice on my 1975 xl125,it is running very poor,it will fire right up but will hesitate for a second when accelerating and this happens maybe once or twice each gear also when i give it LESS than quarter throttle at idle it wants to die??? and when i pull in the clutch it wants to die easy also? any help? maybe the air fuel mixture screw? needle placement? if it is the air/fuel mixture screw what is the factory setting because i have heard numerous people say different things.
thanks guys any help would be great.

what about a plug replacement or a good carb cleaning? if that gas sits in there for a week it could start messing things up. Just the way this crappy fuel is these days.

No offense, and not to insult your intelligence, but there can be a difference between "cleaning" a carb--spraying it down with carb/choke cleaner--and fully disassembling and "soaking" a carb--i.e., fully submerging a carb in parts cleaner for 2-3 days. Carb bodies typically have any number of pissant little fuel passageways that easily clog and don't generally unclog without an extended soak. What you describe definitely sounds like a fueling issue; a full carb disassembly and 3 day soak would surely set it right--the full disassembly is very important because any nonmetallic carb components--e.g., plastic pieces, rubber gaskets/o-rings--won't survive such an extended submersion.
