Thanks, I'll try that tomarrow, please look back at this so I can tell you what happens.

I bought a 98 Shee not that long ago. It started on first kick and ran great when i tested it. Now it will sometimes fire on first kick, but is weak and stops. Other times it is stong and ideals well. But when I run it, it is struggling, almost sounds restricted, has no power and will die easy. Could It be as simple as fowld plugs? I did clean them off last night, but this morning all these problems. Lastly, complression check shows even at about 100. And on of the carbs is leaking out the float valve. Any suggestions??

Thanks for the help!! But I just checked it and I'm at 105-110 even in each. How bad is this? I bought this quad used, so it may have had a top end re-build. How low can it go until failure?

Can anyone tell me what a good compression reading is? I have a 1997, and am trying to tell if it's good or not before selling for a newer one.
