Mower threw a code of PO563, voltage? Could it be the voltage regulator?

You already have another thread on this mower, why did you create a new one? You are making it harder for those folks that were following the other one to help you. Just put everything in 1 thread.

Bought this used a couple months ago with 98 hrs on it. First couple of weeks all is good, but then one day while mowing I cut the blades off and the mower start “missing, surging” it would go from 2300 rpms to 1300 and back up again and again. So I changed the fuel filter and plugs, no change...

Received my new voltage regulator today and installed it and my mower is back. The mower never threw a code until the last time I tried to run it and it was really bad, too much voltage! Hope this helps anyone else that can’t seem to find out why one’s mower won’t run properly
