Thanks for the help with the wiring. I figured I’d start a new post for this one so that people did not have to sift through the last post. I finally got it wired up (I think correctly). The problem was a missing ground wire on the mercury switch. Anyways I have a new issue it seems now. The starter turns but seems kinda slow and does not rise to meet the flywheel. Is my starter shot? Or is this indicative of another problem.

Weak battery, or a loose/bad connection somewhere possibly.

I tried boosting the battery with the same result. I’ll go over my connections again. Could it be caused by a bad wire in the harness? The harness wires are pretty brittle.

If the wiring and connections are OK, the sluggishness could be caused by worn brushes, dirty commutator or tight bearings. Go ahead and take it apart as it’s fairly easy to do and the chances are slim it has ever been serviced in the last 58 years.

What does servicing entail?

Do you have the wiring harness screwed into the motor with the "T bolt?" This is necessary to complete a proper ground.

Where would the T bolt be? On the plug of the wiring harness that goes to the motor?

Look at Mumbles before and after pictures ti see what everything should look like after a servicing. Basically a service is just a clean up and a little lub on the shafts/bushings. Main thing is to get the commuter (brass thing in second photo) clean and the junk out of the grooves.
To make sure wiring is not the issue, you could run the battery leads direct to the starter motor and see if it spins properly now. Connect the negative lead direct to a starter mounting bolt, and then touch the positive to the terminal on the side of the starter. Be careful not to allow the battery leads to touch each other or for the positive to touch anything but the terminal

I would not spray the wires on the commutator with any solvent, the insulation is important and you don’t want to have a low resistance to ground or from coil to coil.

I have gone through similar issues on my 35’s and can attest to the necessity to the good ground. The T bolt is what screws the harness plug into the lower pan on the back side. If it is there you will know it. It is a t handled shoulder bolt that completes the ground for the starter circuit. My poor wiring was found by my starter solenoid clicking and nothing else or a very sluggish starter.

I agree best way to test at this point is to go straight to the starter with the battery to see if the starter is good.

I wound up cutting my harness wires back as far as I could to the male plug on the motor side and soldering on good new wires, but hopefully yours is not too bad,
