I recently picked up a 95 polaris indy, which ran fine when I got it and was able to drive onto the trailer under its own power. But I got back, started it again because I put new fluids in it, had it running for about 5 minutes just to have it suddenly sputter out to die. Where it hasnt started up since. So I poured mix directly into the cylinder but to no avail. Im very new to sleds so im just about clueless as to where to start and what to check. Because it ran strong for the time being just to suddenly die seems wierd.
