I have a JD D110 and the motor surges up and down through all throttle positions. I can see the governor rod moving back and forth. The mower only has 80 hours on it. I have done all the required mtc on the mower so far. Any Ideas on what might be causing the surge problem?

Did you get a completely new air filter? If so your engine is getting too much air and when you get crud in your filter it will return to normal.
No new air filter... It surges with or without the air filter.
I have this model as well with almost 150 hrs on it.
I would check the oil first to make sure it's at the proper level then check fuel flow from the fuel pump. If fuel flow is good then clean the carb.

I checked the oil level and its slightly higher than it should be. Also do I disconnect the fuel line at the carb and crank it?????????
OK will do! THANKS.
I forgot to mention that this was only a problem until it warmed up. But 2 days ago I ran out of gas completely and when I refueled I put stabill in the gas and now the problem is constant. Seems to be not quite as bad when its under load and the deck is engaged.

Absolutely wrong about air filter, read through this:FAQ | Lawn Mower Safety Tips | Briggs & Stratton

Are you sure? Because i got a new air filter and my Kawasaki engine started surging, but today when I mulched the leaves and got dust in it it surged much less.
