Spark plug wires
I am embarrassed to admit that in my haste to put on new spark plug wires on my cub that I didn’t mark them or change one at a time. Is there an easy way to figure out which ones go on the right plug so I get the firing order correct?
Thanks……

Re: Spark plug wires
There are two ways to get enough Cubs. One is to continue to accumulate more and more. The other is to desire less.

Re: Spark plug wires
Hi,
The number 1 spark plug wire post on the distributor cap is in different positions, depending on if you have a magneto, or a Battery Ignition unit.
The picture of the cap Bill posted is turned like the Battery Ignition unit uses.
The magneto cap is turned slightly counter clockwise, so number 1 is at the top.
They are both wired in the same firing order.

The cap is the same regardless of battery or magneto ignition. However, if timed correctly, including governor drive gear, the magneto ignition will line up more consistently from tractor to tractor. The battery ignition uses a splined drive that allows it to be in time in many different orientations. So battery ignition units are less likely to be lined up as consistently, and many do drift over as Glen suggests. There may be other internal differences that cause them to line up differently as well. Just wanted to clarify that both use the same distributor cap.
