Working on my mother-in-laws Power King 1618 with a Kohler K361 OHV. The tractor was purchased 2 summers ago for way more than it was worth and then subsequently overheated on the first day of mowing until the engine stopped. After some minor work on it it is back to running but the valve guide tube seals (guessing) are shot thus it leaks oil pretty profusely and with that I haven't really been able to run it for more than a couple seconds to make any determination on if the engine has other issue also. Before I tear the whole thing apart and rebuild it I thought I would look at just repowering it with something that will be more turn key and less maintenance going forward as everything I have found on the K361 engines seems to be worrisome when it comes to future maintenance (especially because I am not the only one who will be operating it but I do seem to be the only one capable of checking tire pressure let alone oil and making sure the head fins are clean <-no I'm not resentful at all...). With that said, finding anything used to repower this thing in my area seems a lot harder than I expected so I started looking at new engines. I don't really want to drop $1200+ on a new Kohler but I did find a 22HP Predator engine from Harbor Freight that with a coupon I can pickup for $560 and $6.99 shipping.

I also found some video of someone who has fit it into a Simplicity Landlord (not the same I know but the quasi similar application gives me more hope when ordering an engine online that I can't directly examine before paying for it) https://youtu.be/uXIh60k4Ehk?t=1m
I'm guessing that the bell housing on the Power King has no chance of actually bolting right in so I figured I would have to have an adapter plate machined but I think I may have that issue with anything that's not a K series engine. I also was thinking of using a shaft sleeve to bring the shaft size up. (Then again, in the video above he actually turned the engine completely around, not sure on the required shaft rotation on the Power King but this may be an option also (not sure if it makes it easier or more complciated))
