Jack you might find this interesting, I now know that I have the correct engine.
Hi
PaulI feel you are assisting everyone in the KX-A. This is
new territory.
Clearly, the guiding factor with engines is the crankshaft length.
Some makers offered no options; others offered a couple or a bit more.
The limiting factor in this was skirt height of the base. As you said,
it was designed for a 4-stroke.
I guess Paul's great observation somewhat explains the cast and extra-
high adapter plate ... and the 'shaved' cylinder head.
I wonder if that was an SC or Villier's modification.
And that catcher decal hasn't been recorded here before.
The more I learn of the
KX-A, the more impressed I become.
This has been a pretty much forgotten lawnmower.
Many thanks, Paul.--------------------------
