Hi I bought a new Skyhawk Gt5 66cc, and mounted it on my bike. When I first mounted it, the back tire wouldn't move, but I adjusted the clutch, and it's still pretty hard to move, but that's alright. The problem is, is that when I pedal, the motor won't start. Yes there is gas, 25:1 ratio for breaking in. I'm thinking the problem is the cdi, but I'm not sure. I really don't know whats wrong, and I hope I didn't spend $250 for nothing. Please help.
