did some research on lapping valves. went and got some valve grinding compound at lunch. I forgot to get one of those sucton cup tools. I also need a set of feeler gauges.

I figure you downloaded the service manual, but to be sure, when you go to adjust the valves after installing, turn to TDC compression, then back up just a shade to disengage the auto compression release before adjusting clearance. This applies only to the exhaust valve.

Sorry to join the thread so late. I am working on restoring the same Kohler 16hp engine in my Jacobsen UT34004. Same problem. Intermitent starting problem. My points were not making good continuity. Check it across the points when closed with the key on. Your video demonstrates that you do have sufficient compression to run. The engine would have minimal movement otherwise. I almost hope I'm wrong aftero your teardown LOL.

Saturday morning I went out and took out the exhaust valve, It was way easier to do than I had in my mind. Cleaned the block up a little more then dropped in the new valve and got it lapped. Hardest part about replacing the valve was getting those little retainers on.

Put the minimum amount of parts on and then test fired and SUCCESS! Finished reassembly and took it for a spin around the yard. Put a different battery on it, changed the oil to 30wt, and put the side panels back on.

Thanks everyone for your help. Feels good to have it going again.

Didn't see that the other day. Yeah your off the hook now. Anything else that is messed up is probably my doing.

drove it around more over the weekend, and loaded it down pulling a log. It ran great. One thing I have found is the exhaust seems to be louder now.

The louder exhaust would be normal, now you are getting more compression. Glad it is running good for you now :thumbs:

That makes sense since it looked questionable on if the Head gasket was holding 100% along with the nasty valve.

That reminds me, I need to retorque the head bolts now that I have ran it some.

I doubt I will ever buy an aftermarket valve again. May just have been the carbon that was clearly on the valve face, but OE parts are still better.
