The starter box is trying to charge the dead battery at the same time as it is trying to turn the starter. That is a recipe for the exact problems you are having.

Thanks for all the input fellas! My next move will be to disconnect the ignition and test the starter by itself with a good 12 volt. I believe I will find that the starter is just fine..... then on to check my work on the distributor rebuild.

The battery being dead is now a known issue. Put it on the list of things to replace.
If you just want to see if the tractor will run, then disconnect and remove the dead battery and use jumper cables to a car battery (car not running). Be sure to connect it positive ground to the now disconnected battery cables (protect these from touching other metal parts). Turn the gas and ignition on and hand crank the tractor. The 12V battery will just be used to run the ignition system (which will get hot quickly due to the 12V). Your hand crank provides the ability to turn over the engine (not the starter).
Don't put your rebuilt starter at risk. Don't run it long on the 12V because the coil usually requires a resistor to reduce the voltage when running on 12V and it will get hot fast. Don't turn on the lights using 12V.

IMHO connecting a 12v battery to a 6v starter will only tell you if the increased voltage will turn the starter by compensating for some other known or unknown weakness. The only way to know for sure what the condition of your starter is will be to bench test all the components with the correct testing equipment to determine its condition.

I put the starter on a good 12 volt... it spun the engine over just fine! I'll consider the starter fixed for now. Next up is to get a 6 volt tractor battery and the proper cables.

Update: I purchased a new 6 volt battery and proper cables. The engine turns over great! In fact, It spins over better than it ever did when I was cutting grass with it 20 + years ago. I am considering keeping it 6 volt now.

There are many good reasons to switch from 6 to 12 volts but IMHO ease of starting is not one of them.

I am glad it worked out for you.

Excellent! IMHO 6 volt systems are more than enough to handle these Cubs but to each his own. :wink:

:Dito: One of the things it will do is mask other problems that will usually get worse and show up again at a later date. Better to diagnose and fix the issues that are causing the problems in the beginning.
