Machine starts kind of odd, like it's skipping a beat, so to speak. But it starts fine and runs fine.
It just seems like it is making more of a 'dieseling' noise than normal.
Power is normal. Not running hot.
It started doing this one day when it stalled out under load. Clutch machine.
Then it started the odd starting and would not start.
Let it sit for about 15 minutes and it started up, but made the 'skipping' when starting.
I ran Sea Foam in the crankcase and the fuel tank. Changed the oil the next day. This seemed to help some, but it seems the excessive 'dieseling' is still barely there.

Do you have an error code shown on your hour meter?

I’m surprised that throwing snake oil in the crankcase didn’t cure an unrelated issue.

Maybe sea foam in the rear tires would do it.

Why don't you make a video of it doing it, post it on Youtube, then give us a link to see / hear it.
