[AT] Rationale for firing orders

[George Willer]

Frobl,

Actually, your J.D. is neither.  I'm not sure of the correct firing order,
but it is either 1-2- nothin'-nothin', or 2-1-nothin'- nothin'.  If you
listen carefully to the exhaust you can even hear the nothin'-nothin' part.
I think of it as firing disorder!  I wonder If they would have as successful
a collector tractor if they had eliminated the twist in the crankshaft to
make them even firing, or built the other half of the engine?  After all,
the Field Marshall and Lantz are hits at shows when they jump around at
idle.

Most other early tractor makers actually had clever engineers that designed
their engines with each half as a mirror image of the other, so the engines
could run as they should.  :-)
