If the stator was replaced, is your timing advance on the top of the mtr working free and properly ??

Leave the key off, rotate the prop and drop it in fwd gear. Then advance the throttle to WOP. You should see the linkage on top of the mtr moving and the carbs going to full open position.

Pull one plug wire at a time when you have it running and see if you have a dead cyl or two.

Try switching coils.

If it's not the coils it might be a bad power pack. But before you get into the p/p check all the ignition ground connections on the mtr. Coils and all.
