Default Re: Still having heat problems :(

The only other culprit that I can think of is that the timing is too advanced. That could only be caused by the wrong placement of the keyway in the crank shaft or the keyway in the magnetic rotor during manufacturing; unless...... the key has somehow sheared or is missing and the rotor has shifted clockwise as viewed with the mag cover off. That would also make for hard starting, horrible lower rpm performance, but really good high RPM performance.
