Now that you have opened this
We run a little fleet of Exmark Lazers. Our older Lazers from 02 and 03 have Kohlers, our newer Lazers have Kawi FX 801s
We got 3 back in 09 and another in 2012.
first 09 broke a connecting rod in the first 3 months, dealer cover it
second 09 broke a connecting rod after 2000 hours, we replaced it with a new engine.
The other 2.... so far so good.
All of the FX 801s have had the governor seals replaced, once, so far.
2 have had new coils put in.
3 of them have had the choke rod fall off, which means you have to replace the choke shaft on the carb, unlike the Kohlers that use a nylon keeper to keep the choke rod in place, Kawasaki use a metal keeper that is fitted to the choke shaft. The keeper can not be replaced with out replacing the choke shaft
And, the Kohlers have hydraulic lifters, Kawi does not, so at some point you will have to adjust the valves......
The Kohlers, a couple of crank seals. A governor, from low oil..........
I like the Kawi, they keep me in a job
