Thank you for your help. When i first got this atv an cleaned the carb i think the float wasnt quite right an flooded engine. Had some gas come out of exaust donut. Is this an indication that its bad? Is sounds like an engine running without oil. Has a complete top end rebuild. New reeds. New plug. I am new to 2 stroke but i have an 02 that runs allot more quite. Could the bottom end be bad? An how could i check? I am mechanically inclined and have my own shop n tools for most job just didnt want to tear it completely apart

If fuel getting into the exhaust seeped out of the donut you can at least assume it's bad. You may have other problems sounds like.The drive belt could be the problem or the clutches. You can understand a little more about engines and clutches along with the fuel system with a service manual.2003 Polaris Sportsman 90 Service Manual PDF Download

I think the noise on start up is the starter clutch catching or something but would that starter system make noise while quad is running? Also i was told not to run engine without the cover over the clutches. Is this true an will i cause damage if i do? I want to inspect whats going on during starring and running. Thanks
