i have an early 90s craftsman garden tractor that has a nock in the valve systym. it goes away after about 10 minites of hard running.i believe it has hydrolic liters, does that mean no valve adjustment.i am running 10w 30 castrol oil. the nock goes away after its hot.i drained the oil and filed with atf and ran a few minites ;then new oil and filter,still no improvement.
 
That knock may be from the hydraulic valves bleeding off. I have a 27hp Kohler in a standby generator and they recommend 5W30 synthetic oil. Hal

Common Kohler engine problem the lifters bleed off while setting and take some time to pump back up when started.

JD put a Kohler motor in a LX 172 frame and called it a LX173. Kawasaki and JD where fussing with each other so JD bought a bunch of Kohler engine to show Kawasaki that they could get motors else where.

Every single one of them would knock/rattle when first started. I mean real LOUD knock/rattle. The noise would quit after a few minutes of running but they sounded terrible when first started. JD sent out a service bulletin about it. I copies it and posted it on every LX 173 we had in stock. Ended up having to sell them at cost just to sell the first ones we got. Never reordered another one.

Pretty much did not order anything that came with a Kohler motor after that. You had to really want it and wait for us to order it after you would pay a deposit on the machine.
 
I don't know about the older ones but I know the newer ones have a 500hr valve adjustment. If you go to Kohlers website and type in the model number you can get the shop manual for the motor and that will tell you under recommended maintenance.
