HI Nate!

A few things to check, 1. When you put the new flywheel on did you reinstall the woodruff key on the shaft its a little half moon shaped thing that goes on the cut out on the crank shaft its tricky to get on correctly?

2. If you removed the stator which is underneath the flywheel, and replaced the Phillips screws with allen heads, you may have to shave them down as I have seen a few heads too long and it get hung up.

3. make sure that all the coils on the stator are tight if a screw backed out it will allow a coil to move and it doesn't take much to hit the magnets.

4. Lastly with the flywheel off , give it a couple easy kicks and see if its binding with out the flywheel if so could be a bad rod bearing, or a ring snagging a port and not the flywheel at all or a few other things over in the tranny area.

Report back what ya find if anything, making a short vid or a couple pics can sometimes help to solve an issue!

Thanks, I got it working now i figured out that the screw holding stator on was sticking out to much and interfering. Just curious do you know size of the idle screw, because my carb seem to be missing it?

The idle screw is located on the big silver box on top of the carb called the (TORS assembly), you can get to it by removing the seat. If that isnt the one you are referring to see the diagram in this link you should be able to order just about any piece there! Just click the drop down box and click on carb
