I just recently purchased a 124 with the K301 12HP engine. Previous owner indicates a recent engine rebuild. Who really knows but it starts right up, runs great, no smoke. Runs up and down the road without issue. However, when I put it under load it loses power.

For example, I mowed some thick grass last night. It ran out of power almost immediately. If I throw in the clutch pedal (not the PTO clutch), it also takes a long time to get back up to speed. If I am slow to the pedal and let it die, it starts without issue.

However, and this might be a clue:

One time it would not restart. Plug looked fine, checked the high tension lead at the coil. Very rusted connector so I cleaned that up and it restarted lickety-split. Still no power though and slow to recover to full RPM. Continues to restart fine. Governor linkage/action seems to move without issue .

Not sure where to start on this Kohler engine for this symptom. Any idea as to where to start?

Thanks in advance!
