In case anyone wondered what engine this was, it was a CH25S. You can see the model on the cover during the assembly. Great video and very detailed!! Thank you for taking the time to make it! I have a CH20 to rebuild and generally expect it to be similar. Very helpful!!!!

All the cleaning is absolutely worth it. My tool box and benches might be a mess, but what I'm working on has to be clean. The job is always harder when it's coated in filth.

Most excellent video. Have an 800 hour engine, slight knock, low power. Now, I know I can do this. I would suspect that rod and driveshaft bearings on these hold up well and the first rebuild should be similar to yours. Great teaching style with detail, to the point. New sub. Thanks!

I'm curious to know how well those rings seated. I didn't see you use any honing oil and the cylinder walls still showed significant glazing/polishing after you honed it.

Great motors, just stay away from Kohler Courage’s. Command’s are great.

I've never seen anyone use a cylinder hone dry. The stones instantly can clog since they are so fine. Use a light oil in a decent supply when honing to achieve a good consistant pattern and slowly move it up and down to create a crosshatch.

I have ro rebuild a kohler LH685 liquid cooled im hoping its similar to this. They dont make these anymore apparently so we gotta bring it back to life

Great video - for reference, you only need a valve stem seal on the intake side of the engine as that's the side under vacuum. The exhaust side is under pressure so no oil will leak. I confirmed by looking at the parts manual.

I think that engine looked better then it did from the factory

Awesome video. Thanks for sharing your knowledge of this Kohler engine.

Excellent video. I'm rebuilding my Kohler twin and this is very helpful. Thank you.

Very good video. You touch on points that are easy to miss and explain, such as the orientation of the rods on the crankshaft. Thanks.

Fantastic explanation - slow and thorough. I plan to rebuild a CV20 and this will help a lot! Thanks

Excellent video. Very detailed. Thank you. Looking forward to the next video. God Bless.

Runs brand new , Perfect !

I found your channel few days ago, by mistake. I watched one of your videos and subscribed right away! I then saw this video and watched it, glad I did! Since I have same tractor.

Great video ! I am about to jump into a CH20S . Thanks for the detailed video and help!

Great video. Great technique for lapping the valves.

Thanks for the video, Great Job!
