I got this bike with the 48cc motor completely free and ive had it for about a year now but when I fill the gas tank up too full I get gas leakage out of my air intake and my primer..I somewhat understand my way around the stock carb that comes with the motors..any ideas or should I just invest in a whole new carb? Thanks guys. I should also add that when it is leaking so bad the way it has been..I cant start it unless I drain out the float bowl. Then I can open the gas valve again and start it up..but sometimes and sometimes not it will quit it just depends..I drove it 19 miles the other day and had no problems until the 20th mile.
