Gravely 8162B running rough???

[Rowdy Raven]

Hey folks,
I have a Gravely 8162B that was originally built as a prototype at the Clemmons Gravely plant. I had the engine replaced with a 12HP Kohler about 10 years ago. This is my favorite piece of machinery, it runs like a tank... that is until last week when I mowed. It has fresh fuel in it (93 Octane) and it usually takes me about an hour to mow my yard. However when I mowed last week after about 40 minutes it started stalling, it still ran but not strong enough to mow. I limped it back to the shed where it sat until today. Today I cranked it up, it ran great for 40 minutes and at the same place it started gagging again. It finally did just quit. I will try it again in the moring but this is quiet aggravating. Any ideas?????

Thanks,
Keith

The problem could be almost anything. Condenser, fuel filter, coil, valve adjustment, or .....

Most engine manufacturers say that they want their engines run on regular gas, not premium.

When it starts to lose power, try choking it a bit. If the power improves, then the issue is likely fuel supply related.

If choking it does not help, then it is likely ignition. Try giving it a tuneup.
