Ohh how it cleaned up well. The OG yellow was under all the red mud I’m guessing it was yellow and off a cub? Then painted red and stuck on a wheehorse? IMG_1548.jpeg IMG_1552.jpeg IMG_1554.jpeg

I peeled every last bit of yellow off the cast iron block it was a tedious and time consuming task. The end goal was to paint it better then the first guy did... Dang rain and crappy conditions it was sloppy quick paint job. Not my best not my worst. I’m content with it. IMG_1561.jpeg IMG_1567.jpeg

And we come to a near conclusion. This is 3 days of nonstop working to turn a big hunk of junk cast iron into a running k-series that is mostly presentable. Check out picture #3 with that trick coil setup!


I mounted this engine to a base wired the coil to the jeep battery and wrapped a cord around the pulley. With a bit of fuel down the carb throat and a few pulls this engine started thumping away happily. And with that I called it a night. So pumped it ran as smooth as it did. What a treat.

What model is that?
K241 ? looks older than that maybe.
Cleaned up nice, looks great!

Great engines even when they use a little oil as they age.
With Skip on the RPM danger, never pushed one hard.
Current old Cub has the K301

Those were tough old workhorses. I cringe to think about what may happen to it with that Tilly on it.
Does it have magnets in the flywheel?
No coil or magnets internal or external just a solid wheel.

It’s a k181 like my other two kohlers and we push them extremely hard. Magnificent engines. Big block torque often makes me wonder why I’m messing around with small blocks. IMG_0095.jpeg IMG_0862.png IMG_1465.jpeg

No it is a k181 BUT I did get a k241s along with the k181 engine.

This is proof. The bore on these k-series is cast iron and the piston is aluminum. It doesn’t matter if the aluminum melts and self destructs these bores cannot easily be scratched.

Now this modern day stuff we buy scrapes up the bore during the break-in procedure and it’s considered normal…
