Kohler is no more

[Blue Mule]

We bought an eXmark ZTR mower new in 2016. It's got 750 hours on it now and the Kohler Command engine is already showing internal issues. We believe it's a valve issue. It'll act like it goes down to one cylinder randomly, pop and backfire, and generally run like garbage at random times. Other times it's OK.

This engine has had maintenance every season and has been taken care of. I'm not impressed.

My 2005 Command was having similar issues, especially dropping 1 cylinder and running rough. Replaced both coils and problems went away. Not saying coils are your issue but in my case, it took care of problem. 2 coils and voltage regulator only parts I have had to replace.

Trouble is, all the brake parts (for example) seem to be in the same warehouse, bulbs/electrical all in another, etc. I've tried what you suggest and it's never worked.

Sometimes it works out, sometimes it doesn't. If the shipping doesn't make it cost effective I buy elsewhere, but typically I save enough even with shipping that I'm still ahead.

My best buddy had that motor in his mower, and had the lifters go bad. Kohler/dealer replaced them under some secret out of warranty deal.
