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?

JD is best
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.
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.
Yeah mine has done that since day 1 but stabilizes after a few minutes. You may have picked up some sediment/debris from the tank when it ran out of gas.
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.

I have read a lot of off the wall things on here. This one made the top ten.
If it runs good with a clogged up filter then there is a problem. It is the same as running with the choke closed.

If the engine is surging you have a problem with the carburetor in the low speed circuit part of the carb. You might want to give the carburetor a good cleaning. I find a plugged air filter will give you a rich running engine that just runs like crap with black smoke.
