Hello I have a zoombicycles 66cc 2 stroke and am not getting spark. Looking into it and discovered the magnet is off centre. 2 cutouts are not at 6 o clock and 12 o clock. Just wondering how to get the nut that holds the magnet on off. Every time I try to unscrew the shaft turns.

Thanks fraser
 



Installing the magnet, super glue the key in place, let dry, and the magnet won't grab the key when installing the magnet.
 
Here's a slick tool that works great for removing the rotor (magnet).
It's sold at Ace hardware as a faucet handle puller but it works like it was made for removing the magnet on Chinese 2 strokers. The fingers are flat enough to fit behind the magnet and pulls it off without danger of damaging the crankshaft. You need to know that the crank is only a little over 5/16" diameter where the magnet rides and prying on the mag can actually bend the crank if too much force is applied unequally to a side.

This may not be the right way to do it, but here is what I did when I had a motor with a pull start. I stuck a flathead screwdriver between the magneto and the arm of the coil to keep the magnet in place while I turned the nut. once i got the nut off, I used a pair of channel lock pliers to remove the magnet. I dont have that motor anymore because the one way bearing on the centrifugal clutch failed.
 
^What he said. There is no "right" way to do it unless the engine has a provision for it - like a hex on the end of the shaft or a hole where a bar can be inserted - nothing which this engine has.
