I know this isn't a scooter forum, but I'm sure there are plenty of expert mechanics around here.
I have a Chinese 50cc 2 stroke scooter. It's about 3yrs old and done around 3000 miles.
I replaced the cylinder and piston recently, following a seizure after it had been running really well, and afterwards, although it has been ticking over reasonably well (missing a bit), it's got no power when you turn the throttle and dies.
I think it's an electrical problem.
The carb is clean, the petrol vacuum valve works.
I bought a new spark plug, and although I get a spark from the old one, when I put the new one in - no spark. How can that be?
The ignition is a cdi thing, with coils and a magnet on the flywheel. The ignition coil is a sealed unit. I don't want to randomly start swapping bits until I have more of an idea of what the problem might be. Any suggestions anyone?
Thanks
