I just bought a 98 grizzle 600, the only thing wrong is that when the gas is on, gas runs out of the overflow on the bottom of the carb. Is there something I can do to stop this?

 

Check your needle and seat in the carb. and make sure it is shutting off the fuel when the float rises up. Check the float level as well. If the rubber part on the needle is bad fuel will just run into the carb and go out the overflow on the bottom like you describe.

 

Just now getting some time to work on the 4wheeler. Should I start with replacing the float and the needle and then go form there? Is there an adjustment for the float level?
