I guess you've tried re-adjusting the idle (on the thoroughly warmed up engine) and that the bike runs fine at higher speeds.

Starting trouble sounds like not enough fuel is getting in OR the choke isn't operating. Starting requires a lot of gasoline .. a very rich mixture.

Idle also requires a somewhat rich mixture and it would make sense that both problems have a common cause.. a lack of fuel.

A low float level could be responsible for both symptoms.

what about a clogged exhaust joe?

My tummy doesn't feel good right now,

it's clogged too,

now I to go poo.

bye.

thanks for the replies guys. What I did was take off the carb, take apart and clean it, and re-assemble it. I then went around and tightened any loose bolts. I'll recheck my connections for any leaks when i get a chance. I should also mention that the problem is worst when the engine is cold, and it seems to almost go away once it's been running for 10mins or so.

thanks,

Sounds like the machine is 'hunting' at idle. This is usually the result of over-rich mixture, but the fact that it runs better hot tends to contradict that notion. These problems can be frustrating.

If the ped sat a while, it could be lean due to a plugged jet or atomizer in the carb, a manifold or base gasket leak, or leaking crankseals.

About the only way for it to become over-rich, is a problem with the float or inlet valve in the carb - causing flooding, or just too high of a fuel level in the bowl.

One more thing.. I've seen bikes with running problems after storage, that were the result of rodent (mice) activity. One KZ-750 I worked on, the entire airbox was filled up with dog food by the little buggers! Needless to say, that bike ran really badly..I've seen mice do things like this several times, on equipment.

i found a chipmunk in a 1991 Chevy Lumina Z-34 i had bought as a junker to work on. the little booger was still in there when i took the filter off. then he ran like a bat outa hell. once i replaced some intake sensors that car ran like a top lol! so it's very possible!but it sounds to me the carb float is messed up!
