John,
You have the firing order correct. Number 1 cylinder is the one
nearest to the flywheel in the left bank of cylinders, when viewed from
the flywheel end of the engine. Number 3 cylinder is the other cylinder
in this bank. Number 2 cylinder is the on nearest to the flywheel in
the right bank of cylinders and unber 4 is the other cylinder in this
bank. The cylinders are numbered from 1 to 4 on the air shroud near the
spark plugs.
If you have a half-speed distributor, Number 1 is at the 12 o'clock or
nearest the engine block. Rotation is counter-clockwise and the spark
plugs towers would be in the firing order. 1,3,4,2.
If you have an engine speed distributor, Number 1 is at about the 2
o'clock position with 12 o'clock being closest to the block and the
position of the coil lead. Rotation is still counter-clockwise I think,
but the spark plug leads are numbered 1,4,3,2.
If you have a magneto, Number 1 is at 2 o'clock. Rotation is
counter-clockwise and the leads are numbered 1,4,3,2.
Sure do wish mine had an electric starter!
