Definitely clean out the tank..... 3 yr old gas is typically bad and will gum things up anyway...... You may end up having to remove and clean the carb out very carefully to get things to perform correctly..... maybe a carb rebuild kit would be a good idea at this time too.

2 years? You definitely have to clean the tank and carb! Watch out though, since it was out for two years, you might have to change some parts of your bruin (i.e. gaskets).

Even after cleaning your car and gas tank I would still run Sea Foam though it!

Yea I was so stoked when it started but I will not ride it until I put the new oil seal on. It's worth the wait. Don't wanna freeze it up again. Thicken about getting either the grizzly 550 or sportsman 550. But idk hard choice.
