Got the motor back

[Country-Boy]

Back from the shop is my kohler k161 for my IH cub cadet 70. Bored .020, surfaced, valve job, etc… $150. I guess I’ll start with govenor adjusting. When it was running it was always running at super high rpm. I see the nut was loose, I don’t remember loosening it and don’t know if the shop would have had to. Just made it tighter. Does this look fine? From what I read in the manual, I think final adjustments are made while running…?

The position of the governor arm on the governor shaft needs to be set once the carburetor is installed following the instructions in the Shop Manual to get the motions of the governor mechanism, and the carburetor butterfly shaft "in sync".

The adjustment procedure begins on .pdf Page 52 in the official Service Manuak linked below.

The nut you speak of, I guess is the nut behind the clamp bolt on the governor arm. With the engine off the chassis it is easy to bump the arm and loosen that nut.
There is a coiled spring behind that round disk with the holes in it, isn't there? That is your governor spring. One end of that spring should hook to the disk with the holes in it. The other end should hook in or around the governor arm.
After you adjust the governor travel that W.O. mentinons, then you move the arm to set the speed the engine runs. I am thinking you conect the throttle cable Z bend to the hole in that disk and then clamp the cable to the arm. To go faster you loosen the nut and turn the arm counterclockwise. To go slower you turn the arm clockwise. when you reach the desired wide open throttle speed. (I am thinking somewhere around 3200 rpm. That Kohler manual will tell you.) Tighten the nut.

How hard was it to find piston, rings etc? Got a k161 to do on my son's original.
The last Kohler I did I think I got taken to the cleaners on at the machine shop. Same shop did another one for me, same amount of machine work same kind of engine, and didn't charge me as much as the most recent one. Which cost me $300 just at the machine shop before I even started buying parts....

Assuming the work they did to your motors is similar to what they did to mine, you need to find a different reputable shop...
I got all my parts including rings from isavetractors. It's supposed to be the best aftermarket brand out there. I've only heard good things about them. However their price definitely reflects that. Might be able to find nos Kohler on eBay or a bunch of aftermarket stuff online.

Thanks for the info. I don't see a spring in that location...

dont know what they did to yours but they did the same amount of work to my first one as the most recent one....
They did do a Slant 6 for my truck in between, they have always done me good work I was just surprised at the higher price on this most recent K301 Kohler vs the one they did for me before. seems like the first one was like $175.... why the most recent one was $300, I dunno. I have all NOS parts on hand for this one, just gotta get it all put back together...

I had four sleeves, exhaust valve seats and 8 guides put into a Hercules for $1200.
I work in small engine repair, a lot of parts have gone up 20 to 30 percent or more since The Disease and 2020.
