I have questions concerning my 2005 Arctic Cat 500 (manual transmission) I'm new to quad repair but a quick learner. I recently replaced all top end gaskets and seals (all thanks to a blown head gasket) now after changing the oiI a few times noticed gas in my crankcase. How do I go about fixing this?

Im not sure this is the problem but you can check:::

There has been many carb problems since ethanol. It seems that it makes the float needle not seat correct/stick. The carb fills up with fuel and then fills the motor.

If this is happening, try shutting the fuel off and let the carb run dry when done riding. It seems to help.

Thanks for the information bud, I did an overhaul of the carb but still had the same problem.

After all that work, it turned out my air filter was to blame. I cleaned it and now the quad is running like a champ. The lack of air was causing the engine to run rich.
