Looks like it's definitely a K series engine
Check the head bolt pattern to help narrow down the ID:
6 - K91
7 - K161 or 181
9 - K241. 301, or 321
10 - K341
Here's a link to the K series shop manual http://www.kohlerengines.com/onlinecatalog/pdf/tp_2379.pdf
Thanks Bert, that really helped a lot! In looking through the shop manual and an owners manual I also found online, I've narrowed it down to the K161 or 181, either 7 or 8 HP. The only difference I can find is in the stroke length. If I think of it, I might go ahead and check, but whether it's the 7HP or 8HP doesn't really matter much at this point, as I find I'm running at less than 1/2 throttle and doing just fine with it. Relatively quiet and sippy on the gas compared to WOT, which is nice. Started first pull every time today! Gotta love that and the easy pull that was easily accomplished left-handed and off angle too!
It's nice to have the manuals though for any future repairs. Thanks again for the help! :msp_thumbsup:
