getting frustrated

[beakerlsc]

ok i posted a month or so ago that a 400ex i was working on wouldnt start... i found the problem and fixed that (it had a loose connector on the cdi) since then i have had it running and now once again it wont run... i know it has spark, compression, and is getting fuel. The spark looks good. I managed to get it running for a little bit by pulling it around with my banshee. now it doesnt run again. i checked the valve lash and the timing and its all fine... i cant figure out what else it would be. if anyone has any suggestions that would be great.

SO YOU SAY YOU HAD IT RUNNING A LITTLE BIT? DID IT RUN LIKE SHI* WHEN YOU HAD IT RUNNING BEFORE OR WAS IT RUNNING GOOD? ALSO DO YOU HAVE A KILL SWITCH? I KNOW YOUR PROBABLY THINKING THAT I AM RETARDED BUT JUST CHECKING OVER ALL THE BASICS TO MAKE SURE THAT IT DIDNT COME UNGROUND OR MAYBE ITS CUTTING IN AND OUT OR SOMETHING.
