My thought is you need a new "bendix" for lack of a better word. The device I speak of spins out and connects with the flywheel. There is the possibility you have electric problems but based on what you say, I think it is mechanical.

I have a tractor like this too. A lot of the problem is the RPM of the Starter shaft. Make sure you have a 6 Volt Armature if you are still running the 6 Volt Battery. There are 2 different Bendix drives, the old style which is the long style and the newer Automotive short style.

To get the shorter Automotive style to fit inside the Bell housing you have to use a Die grinder and make a little room. You may find the Website, Dennis Carpenter.com beneficial. Valu-Bilt is another tractor parts source.

There is a referral to an Improved Ratchet type Starter Drive. You might ask the Re-builder if the part you have is suppose to fit an NAA type tractor. My books show it would be the wrong part if it does. I have read a lot of Parts books and seem to remember some of the Bendix gears were 9 tooth and some were 10 tooth. Your Ring gear is suppose to have 134 teeth.

I believe you are better off testing the Starter before you install it. You may want to check the Starter Draw on a bench at Autozone or Oreillys. The lower the draw, the better the connections are. If you are dealing with a Tractor place, they can certainly bench check the unit.

You may need a stronger Battery with more pop in it Have your Battery load tested too, you may be surprised. When I rebuilt my 8N starter I really did not care for a few plastic components I found inside it. You are going to need to lube up the Bendix good to keep it sliding.
