Engine bogs down in high or thick grass more than it used to. I put sharpened and balanced blades on almost every day. Have replaced two spindles that were bad. Seemed to help a little. Replaced the fuel pump (and filter) at suggestion od dealer, helped some. Checked valve lash, was a thousandth off or so, set as close as I could. Don't know how critical this is. Changed plugs, they weren't bad. Always cleaning and changing the air filter, changing oil and filter when due, etc. Being an EFI engine, I don't know what else to check or do. Any suggestions on what to do next, before I take it to the dealer, which I really don't want to do. Two weeks before he can get to it, etc...

Make sure deck underneath is clean as well..

have you verified its running on both cylinders? take a temperature gun and compare heat readings from cylinder to cylinder OR start the mower up, get to operating temperature and pull a plug wire off of a spark plug, if the engine stays running, put it back on and pull the other one, if it dies, your other cylinder is dead.

Thanks for the replies, guys. Yes, I clean the deck everyday. Hadn't thought about checking for a dead cylinder, but will do that later today or tomorrow, but don't think that is the problem. Cutting the grass in question at 3 1/2", have had to go to 4" sometimes, just to finally get it done.
I think I read there are 7 sensors on the EFI engines, and there really is no way to check them without the software. I didn't know if there was anything else I could check on the engine.

And it not just the software you need but the electronic interface. And is fairly costly except for the dealer that can justify the cost. But the software is cheap that goes with it is cheap.


Which why I have not purchase it myself as first I got to start seeing the EFI engines in my shop first. Then I will part with the $410.
