i have a 1994 polaris indy 440 supersport. she will start up on any normal morning and run like a beut. i can get off go inside for somehting and start it right up if its only been sitting about 10 minutes. but. if she sits for over a half hour and the engine cools back down it wont start uup easily. i always need to replace the plugs and keep pulling then she comes to life. any clue on the problem?

All you do is choke it, (flip the choke lever up) if its been sitting for 1/2 hr or whatever, then get off the choke right away.
Simple.
Not a big deal.[:)]

That might work!!

Maybe fuel leaking into the engine. Try this, Turn the gas off a few moments before shutting the engine off. If it starts back up easily after turning the gas back on then you most certainly have fuel leakage. It's worth a shot and it's an easy test.

I agree with butcher boy. Or another thing could be wrong with it, maybe electrical problems?!! WL

Are you swapping old plugs (from say a couple days ago)? Or are you putting in a brand new out of the package fresh pair every time? If you're swapping old plugs for old plugs, you may have an issue with the insulator being cracked.
