Engine Swap was a success

Recommended Posts


The engine swap I have done this year when I have had time was a success!  The tractor when I bought it had a k301 that was really worn out to the point I would dump a 1/4 bottle of oil in it everytime I started it for the day.  This new engine runs like a champ!

That K361 is a brute equal to or more power than a M20 twin.  Just keep the head fins clean!  Did you make your head cover/shroud easily removable, for cleaning?


Yep, all I have to do is take the spark plug lead off and it comes off.  It has been running erratic when I have full throttle and full ground speed.  The engine may be a little tuned up and the jet may be drilled, and getting too much fuel. Do you think a jet from a k301 carb would work?

If original the stock carb is the biggest (throat dia) that Kohler used on the K and KT engines.  Most tractor pullers put that carb on the 14 and 16hp engines (to run higher rpms with a steel flywheel of course).   If a cast iron flywheel it would have only been modified for alcohol or ethanol blends, no benefit otherwise.

I would  play with carb tuning and points timing.  This engine is  a little fussier than the flat heads are, or maybe you can really feel/hear the difference with the right tune.

For instance I have found mine runs the best with the points set at .017 vs the recommended .020, and logically this makes looking at where the spark plug is vs. the flatheads.

      Hello glad I got on this site. I hope to upload a couple of photos of my Simplicity Broadmoor 
      Model 707 Tractor. I have replaced all the belts on it and installed a new ignition switch.
      Have a mower deck which was in poor shape , repaced a couple of bushings and welded the
      deck where there was some holes. The tractor and mower deck came from a friend and the 
      mower deck metal was getting pretty thin. Some new metal was put in it and we also undercoated the underside of the deck. This was done by my friend Greg Toulman.
      I have not put the mower deck on the tractor yet, waiting for Greg to come home and give me a hand. Can you please tell me if there is a manual for the mower deck and where I could get one.
      I would also like to get some moon wheel discs as well.
      I will try and down load some photos of the tractor when my wife shows me how to. 
      I really love driving this tractor and also how well it is made compare today's tractors, especially the flexible rear end and the rollers.
      Tell the next time
