I have a 80cc/66cc Silver Slant. Ive only had it for about 4-5 days, and I finally just got it installed considering I work 6-7days a week. It hasnt been started yet because the back tire is "locked up"(not spinning at all) the tire at first spun literally only half a rotation. Now it won't spin at all, not even with the clutch handle pulled in or with the spark plug taken out!! And it's kinda upsetting considering its my only transportation to work!! any thoughts or ideas what it could/might be?? Please someone help me!!
