i recently got this 4 wheeler. its runs good but pours gas out of the over flow line on the carb and when i punch the throttle it dies, also backfires sometimes. it runs great other than that. also with it being such a older model is there a lot i can modify on it? it already has independent suspension in the front, a mono back shock. its a 5 speed also if that matters. any help will be greatly welcome. thanks.i recently got this 4 wheeler. its runs good but pours gas out of the over flow line on the carb and when i punch the throttle it dies, also backfires sometimes. it runs great other than that. also with it being such a older model is there a lot i can modify on it? it already has independent suspension in the front, a mono back shock. its a 5 speed also if that matters. any help will be greatly welcome. thanks.
