05 Vinson 500 quad
 

Need Help Please !!

Will start but immediately goes dead.
Any Ideas ?

Sounds fuel related, or carb related. First check that you have plenty of gas getting to the carb. When I got my Arctic Cat, previous owner must have left the gas cap off, and the tank had lots of crud in the bottom. Next would be give the carb a good cleaning, and make sure the float height is correct and the right jets are in place. Switch to reserve and try, btw. I've had the same issue when tank was low.

I'll be sure and check the fuel situation for trash and clean the carb..
Thx for the Info hydrex
