1949 Cub plug wires

[zig79]

Please understand that I am not a mechanic, so much of what I am asking is learning on the job. I need to know how to wire my spark plugs to the proper location on my distributor. I took mine off to replace them with new ones and, well you can guess the rest. I have them out of order. Can someone please help? Photos would be an added plus. Thank you.

If you have 2 posts you can download the original manual from this site and it lists all the info you want and more.

Hi,
In one of your posts you have a pic showing your Cub has a magneto, with a replacement coil mounted lower than the magneto, so the original coil in the magneto is not being used.
The post for the original coil is on the top cover of the magneto, the post is open in your pic, because the spark plug wire is going to the newer coil.

A Cub magneto originally has the post for the spark plug wire for number 1 cylinder at the top on the magneto cap.
Sitting behind the magneto, facing forward, the firing order is 1, 3, 4, 2, going clockwise around the cap.

Number 1 cylinder is at the front of the engine, 1, 2, 3, 4, going from the front to the rear of the engine.

The Cub owner's manual has info and pics about the magneto.

Hi,
The Cub owner's manual can help you learn about maintenance that the Cub needs.

Below is the 1949 Cub owner's manual. The experts on here recommend people read it. It has lots of info about operation, maintenance, and lubrication. There is a table of contents on page 1.
It shows how Cubs originally looked in it. The lube section begins on page 14.

It shows the electrical system that a 1949 Cub originally had.
Cubs made before mid 1964 originally had 6 volt, positive ground electrical systems.

It has magneto info on pages 30 - 32. It shows how to get to, and replace the ignition points, and set their gap. The points get burned from use, and the engine won't start good, or run good if they are burned enough.
It shows how to time the magneto to the engine also.
TM Tractor at the bottom of the page has new points and condensers.

The 10 weight motor oil mentioned in the manual for the Touch Control was changed later to Case IH Hy-Tran fluid. It is sold at Case IH dealers.
There are other brands, be sure it works with IH hydraulic systems before buying one.
The manual tells how to check and change the Touch Control fluid, and remove the air from the system.
Be sure to check the fluid with the arms in the rear, or down position, the manual says to also.

I would check or change all the oils before using the Cub. Using it with low oil in a gear housing can damage the parts in the housing.
There are 3 separate gear housings, with 3 separate oil levels to check, in the rear area of a Cub, the transmission, and 2 final drives.

The transmissions in Cubs commonly get water in them, from rain, or condensation inside the housing over time.

The air cleaner is an oil bath air cleaner. Dirt that is sucked in settles to the bottom of the oil cup. It should have clean, light motor oil in the oil cup to work right.

There is a search box at the top of the page, to the right of the Farmall Cub, you can find info in posts that have been made.

In the future I would suggest that you label the plug wires with a piece of tape or maybe a label maker. It makes replacement much easier.
The service manual on this server will show you the cable routing.
