That's where the progress stopped. It appears I don't have a governor any more. It won't kick in to bring the engine back to speed when its loaded, and sometimes when it's sitting at idle it starts to speed up and could possible over speed if I don't lower the throttle setting. I noticed when I was sliding the brass nut off the shaft it caught on a burr and the cross shaft came with it for about 1/4". It slipped back into place but I don't know if it's in proper alignment.
I also found oil leaking around the governor gear retaining bolt so I removed it and reseald it. My understanding is that the only purpose of this bolt is to hold the gear in place when assembling the engine. I don't know if the linkage adjustment is delicate and I just don't have it yet, or I pulled something apart that's going to require some serious disassembly. The initial setting procedure in the manual looks pretty crude but maybe I'm missing something.
Any insight would be appreciated, Thanks, Projectnut

Great News !!!! Glad you found your problem and everything is running well again, Al
I'll second that. Great when something that frustrates finally behaves itself.

What you might also find is it leaking a considerable amout of oil due to the worn shaft, remove the nut, place a couple of small o rings on the shaft and screw the nut back in. It won't fix it totally but, it will slow down the leak. (if yours does)
One other issue, if I recall correctly, my Kohler manual does'nt state when setting up the governor that the throttle needs to be in the full throttle position. That step makes a huge difference on setup. (duhhhhhhhhhhhhh)
Have fun...........those are GREAT little tractors........you'll love it.

Setting the governor was a learn as you go experience. I have 3 different Kohler manuals covering the procedure and they all differ depending on the age of the engine and make and style carb that's installed. Mine happens to fall between all the cracks. It has a replacement early style Walbro. It has different linkage than any covered in the books and also has adjstable main and idle jets.
I think the main problem getting the adjustment right was that the cross shaft was slipping slightly before I got the linkage tightened. By holding the shaft with the vise grips I was able to put enough pressure on it for it to remain stationary while tightening the linkage. I took it out again yesterday and everything worked fine.
The next test is to load the trailer with wood and climb the hill to the house. It's not as steep as the one where I'll be using it but it should be a good test. The next step is to build a bracket for front weights. I'm sure it's going to need some since my JD does doing the same job.

After I returned to the garage I got out the maunal and did a little reading. I don't know what year they started installing the combination valve, but my book says you should put the motion control lever in the retard range when descending hills. If the hill is too steep you can even shift it to the reverse retard range to slow or stop things. I gave it another try with the engine at 1/2 throttle, low range, and with the lever in the forward retard setting. The machine slowly crept down the hill without gaining any speed whatsoever. By the way I also adjusted the brake band before the test just in case I needed a little extra stopping power. Since then I've gone up and down the hill several times without any problems.
Next week I'll load the trailer (actually an Agrifab 1,000 lb capacity garden tractor cart) with a few hundred pounds of wood and give it another try. I was going to do it this week but had to make a few modifications and repairs to the trailer. If everything works well I'll make a front weight bracket for the tractor and put it to work. The nice thing about where I'm going to use the machine is that it always goes down the hill empty and up the hill with a load.
