pacer 3,159 #1 Posted June 28, 2022 Had this old K241 sitting over in the corner for .... 6-7-8 yrs? Seemed I set it aside because the governor was wonky thinking - as usual - gotta tear into that and see whats what, and, well I finally did. And cant find a thing wrong with the governor so decided to ck out every thing else while I was that deep into it. Checked the crank first, it had this odd little ... streak? showing on it. Get the Mic out and .... whoa! check out the pic and that reading - 1.499 (one 9 got cropped) I have NEVER ran into that good a reading - remember new is 1.50 +- .001. Now the .. odd little streak, dont know what it is, seemingly just a dark spot, checking with the mic all around and cant seem to indicate any thing. rubbed it a bit with some 600 grit and didnt faze it, and rod looks OK. So, next wanted to ck the cylinder and ..... whoa, again! Check that reading too! 3.250 is what factory is! I went up and down the cyl and every reading was the same - 3.25. I cannot remember the origins of the 241, just that it was a pretty decent little tractor, and I remember I had a K341 that needed a home ... soooo. I'll put this thing back together see if I can sell it. I must have went back 5-6 times re checking my readings, just couldnt imagine they could be accurate! 10 Share this post Link to post Share on other sites
Snoopy11 5,713 #2 Posted June 28, 2022 That crankshaft reminds me of something I saw on an LS forum a while back... A momentary oil starvation is all it is... nothing to be concerned about... Might consider polishing with a micro polishing cloth... Don Share this post Link to post Share on other sites

pacer 3,159 #4 Posted June 28, 2022 Dang, Snoop, that really does look very similar to mine, I'll take another run at it tomorrow. Thanks 2 Share this post Link to post Share on other sites
pacer 3,159 #5 Posted June 28, 2022 @Snoopy11 I couldnt wait til tomorrow to take another look at that --- whatever on the crank. I tried buffing with no change, and since that didnt faze it, I took it over to my pretty strong magnifier and gave it a close look see ... I really cant figure what it is, unless maybe it is a discoloration of a quick hot swipe of oil, I cant see anything except a very flat, smooth crank journal -- with a dark stripe! 3 Share this post Link to post Share on other sites

oliver2-44 8,852 #7 Posted June 28, 2022 Looks like it will be a great engine. Run baby run! @pacerIs it a Starter/generator K or a later electric starter setup? Share this post Link to post Share on other sites

I'd put a dab of muriatic acid on a rag, and rub... JUST to be sure... BUT... if you don't feel anything with your fingernail... like Kevin said... it may not really be there...

953 nut 51,682 #9 Posted June 28, 2022 Could it be a smudge from some plastigauge that wasn't removed. 4 Share this post Link to post Share on other sites
pacer 3,159 #10 Posted June 28, 2022 @Pullstart Cant even come close to feeling anything, and mic-ing all around the area gives the same reading. Its like its .... dyed? in the metal. @oliver2-44 Its the lectric starter model. 1 Share this post Link to post Share on other sites
