I have an older Exmark Lazer Z HP that seems to be losing RPMs for no reason. It is from about 2001 - 2002 timeframe. The Engine is a 21hp kawasaki.
It will seem to be running just fine, then all of a sudden, the engine will sound like it is bogging down and the blades will start losing a bunch of rpms. This happens whether I'm going thru grass or not. It will sometimes do it whether the blades are engaged or not.
After a while of this, it will just pop back to full RPM and seem to run fine for a while, then it will do it again for no reason.
Could this be a fuel pump or fuel filter issue? I had it to the shop, but of course it wouldn't do it while they had it.
Should an exmark repair place be able to fix that? What kind of cost am I looking at if it is a bad coil? Anything they can do to test the coil out? As I said, it didn't happen the last time I took it in to them.

If they have a good service department. They should be able to fix it. Coils are anywhere from $50 to $100 plus the labor to fix. Usually the start breaking down. Not doing it all the time. But as time goes by. It will go out
