I can't keep it running...

[Darren]

Hello all,
I recently purchased an 04 GZ250 that "Didn't run right" from a friend. Her account was that it started an ran fine, then one day it would start and idle but would die when given throttle. After some research it seemed that the pilot jet was plugged. Whne I got it home I could get it started but it ran at idle speed only on full throttle but would eventually die and not start.

I got a carburetor rebuild kit off the internet and cleaned and rebuilt it. One thing I noticed was that the choke/enrichiner diaphragm wasn't all the way on and there was no suction if I moved the slider with my finger. I got it to suction after a bit of fiddling.

After I got it back together, I tried to start it and it started but idled really high so I adjusted the idle speed down a bit. When I thought I got it right it died and back to the same problem as before (idle speed at full throttle).

I thought that maybe the diaphragm for the choke/enrichener came off again but after I removed the carb it still had suction. I put the carb back on (no other cleaning or anything) and again started and ran at a high speed then petered out.

Any Ideas would be appreciated, Thanks.

Oh and what does the choke symbol mean, is forward open and back full choke or vice versa?
