ok I started over AGAIN for the 6th time at least.  

I took off the gas tank and made sure it had spark.
It was very strong and I could see the actual spark so I put the gas tank back on and removed the bottom of the carb and switched to primary and gas did flow thru the carb..   I fully charged the battery and tried to start it.  It makes a occasional chug that is very soft.

Im thinking my carb is messed up because I've got spark and I removed my air filter.  I blew thru the carb vent tubes and made sure they werent clogged.  I even bought a new gas line and connectors for it and the vacum tube.  The vacum tube looks brand new and no holes are in it.

I tried to start it on primary. I tried to start it on regular. tried to start it with the choke on and off.  Heck i felt like I was preforming cpr when i was blowing in the carb vent hose haha.  I know my decompression valve is working because I disconnected my starter and I could hear it engage.  My float in my carb is working properly and im waiting on my manual so I can take the carb off and clean it.  I did see a hose unplugged under the bike that looks like it some kind of drain hose.  It was as big as the fuel line and Ill take a pic of it tomorrow.  Im not giving up because heck my bike is a 95 with only 7k miles on it.  It ran strong before it quit.

Lets see when I got gas and limped it home it was driving really rough.  When I engaged the throttle it would sputter and act like it was starving for air or something.  one second it would bog down and the next it would launch forward.  very rough and kinda scarry when traffic is behind you and u cant maintain a speed.

Im thikning somehow the air delivery is not getting to the carb somehow..  I hope this helps and sorry I didnt post yesterday I couldnt work on it.  But I will tomorrow if you have any suggestions.

hey there, im going through the same thing with my bike!

i just removed the drain screw on the bottom of the bowl, clean gas came out. however... even though i had the petcock on prime no more gas was coming out of the drainhole. what does this mean?

full bowl came out, fuel flows out when i pull the hose but not when i pull the drain plug. also it doesnt pour out of that hose, its a small stream

progress!

i decided to start fiddling with the air/fuel screw, turned it almost all the way out and got it to turn on, idle for about 30 seconds then died. started up again a couple times for a few seconds then died again. im about to kill my batt so im letting it sit for a few mins before i go outside and meddle some more

edit: the settings i have right now are, PRI and full choke and air/fuel almost all the way out.

got a nice backfire too, scared the shiat outta me  

i do have gas in the bowl. fuel is flowing from the petcock fine. battery just died though. have it on the charger and hopefully will be able to start messing around in a few hours.

i believe my starter is pretty weak, i listened to some other audio clips and mine is ALOT slower than theirs. could a weak starter cause my battery to die all the time, well at least quicker than i would imagine it should.

brand new battery, im using a 1.5 amp trickle charger

sounds like an idea.

today i put the batt back, i can get it to fire up on first try. however it seems to idle for about a min then cut out. then it has a hard time starting back up for any longer than a few seconds. i leave and come back about 15 mins later and shell start up and idle for a min or longer again

seems like somethings heating up and causing the bike to cut out?

edit: after re-reading your post. the valves seem like a probable item. if they heat up and then seize, sounds like whats happening to my bike. have you done this adjustment? i would have to order the feeler gauge but do i really need all those other tools or could i just get it done with some basic sockets/hand tools
