Hello, So you are saying that the starter engages but only clicks?
If so it would have to be a current delivery issue to the starter. If it made no noise at all or failed to start when spun it could be that the 2 small lead wires on the selinod are in the wrong position. I have done that myself when in a hurry and then stood back for a while and went what's wrong. I am not sure if this will help you or not. Jason
