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!
