Ok...will stop by TSC after work to see if they have in store. Thanks!
I picked up exact kit, and lightly coated green foam cover and slipped it over new air filter. But when I was tightening cover down, it wasn't going down all the way, as I could see inside all around. I wish I had noticed it earlier, but I pulled old filter out of trash to find that the new filter was taller. I thought maybe I grabbed the wrong kit, but doubled checked and it was correct and also found on my engine it is Kohler Command 18S. I doubt TSC will swap filter since I can't return green foam along with it, after rubbing light coat of oil over it. Just my luck that kit would have wrong size air filter in it.

CH18S should be what you have, that is what is in my 1864 (same as yours but with couple extras). It's the correct kit...👍😎👍
The engine is a Command 18S, so why would I have the wrong size air filter, which was right diameter, but taller than existing one and couldn't seat cover afterwards. Do I have to worry about oil filter possibly being wrong type too and causing issues please? If this kit also works with Command 18S, why wouldn't kit list it? Hoping TSC will swap air filter with what I need.

Manual says SAE 10W-30, so does it have to be Cub Cadet brand, as I read it contains higher zinc levels to help cool engine or can I also use regular automotive SAE 10W-30?
Had earlier issue with engine overheating, white smoke and Low Oil Pressure light on. Engine would shutdown 15-20 seconds after starting. I replaced Oil Pressure Sensor, which fixed issue shutting down, however engine still gets hot. After removing massive mouse nest, I had hoped it would have fixed overheating issue. I did notice small Oil area on right-side of engine and little bit of white smoke coming out of breather. Is it possible the overheating caused the leak? I don't have any Oil accumulating anywhere.

You got to clean out all the fins and remove all tin covers to do it right, the over heating may have got you head gasket damaged, and a upper ring landing cracked, you have to keep the fins blowed out after the first good clean out !!!! To keep the engine temp in the working temp range, and keep any air screens cleaned out !!!!

Try not to use automotive oil in small air cooled engines. Oil for these small engines should be low ash, and has proper additives for heat and wear. the proper recommended oil does not cost a lot more. Main thing is that it is full, and changed at the proper intervals. Also use quality oil filters.

You are correct......during process of replacing both head gaskets, I had discovered engine cowling tightly packed with mouse nest. After removing nest and installing new head gaskets, engine no longer overheated and could actually feel air circulating from engine running. Now I have traps all around my cub hoping to prevent this from happening again! Thanks

Thanks and yes, after replacing head gaskets and cleaning out mouse nest from around engine cowling, I picked up proper engine oil below, from TSC.

No bugs, no rats, no bad snakes, you keep the place right !!!! Always preferred king blacks to rattlers or Cotten vipers !!!

Hats off to your Dad for his service! Up in Northwest Ohio, we don't have any snakes like that and now with cooler temps mice will be migrating into the barn. I need to get some barn cats and see how that goes. Thanks

Bounce dryer sheets will keep mice away for about a month, then need to change them if you have a lot of mice in the area.
I didn't know that......thank you! I have some dryer sheets, not Bounce, but figure they'll work the same and will try those and see how they work! Much appreciated!

You need to pull the tin covers on the engine it’s going to be over heating and wiping it out, the air can not flow around a plugged up air system with all that debris !!!!
