[Farmall] Timing setting on Cub

[Mike Sloane]

The rotor should point to approximately "2 o'clock" when firing on 
cylinder no. 1.

Remember that the piston will be at TDC twice for every revolution the 
distributor shaft, so you could be right on the money or 180 degrees 
out. You need to stick your finger over the spark plug hole and feel the 
pressure building up as the piston rises. Then you will know that you 
are on the compression stroke. If you are 180 degrees out, you will have 
that backfire problem.

Also, make sure that your firing order is correct and that you have the 
direction of magneto rotation correct (I got is backwards once and had a 
heck of a time figuring out what was wrong.)
