This is what I have found on the valves
Do I set them at TDC?
Can I do them like I do a Briggs one valve open and one closed?
First Kawasaki I have had. Started getting a puff of smoke just on start up. And not every time.
If smoke under load, rings/bore. If on throttle after coast, maybe guides. Sensation of power can exist with bad rings.

Yep, sounds like valve guide. At idle the engine has the greatest amount of vacuum. This is when it is most likely to suck some oil down loose valve guide(s).
When you throttle UP, is this when you see the blue smoke most ? (as motoman posted)
A 'Leak Down test' would let you know if your valves are not seating properly, & if intake or exhaust, or the rings are the culprit.
Well...hmm...half quart per hour is a lot IMO. My good running Intek 24 will consume about 4-6 oz per hour (no smoke), but using 5W-30 synthetic. So maybe both guides and rings??
Valve seals work well . I have had a car engine which pulled enough detergent oil through exhaust guides to clear a little channel in the carbon ring in the exhaust port. Usually mfgrs put the guide seals on the intake, but I note my Intek has a seal on the exhaust guide only. And yet any cooling by oil should be on the exaust as the intake is way cooler via cool intake mix and distance from exhaust flow. And the intake vacuum should work stronger on the intake guide. So...:confused2: Someone please "splain" it for me.

This is what I have come up with.
This is the second Kawasaki engine that lasted less then 500 hours.
Going back to a Briggs.
Toro is going to replace it then I will sell the mower.
