Hard starting Allis WD

Having issues with starting WD with the starter. The tractor is 12 volt with a magneto. The tractor only wants to pop when using the starter. Tractor starts fine when pull started. It also starts good after the tractor is warmed up. Carb has been rebuilt, new battery and cables, new plugs and wires, new mag cap and rotor.
 
You can put in all the new parts you want but if you do not know where the problem is first you can cause more problems. Are the new plug wires the true copper wire plug wires or the ones made for a car or truck which will not work on a tractor??? What does you spark look like?? It needs to be a blue/white in color and jump a 1/4 inch gap or more.
 
The plug wires are the true copper wire plug. There is good blue spark that jumps when a plug is removed and grounded on frame.
 
We had the same issues in the 50s- WC and a C. Pull start three feet and it"s running. Mag needed rebuilding.
 
But will it jump a 1/4 inch gap or more. Do you here the impulse click when it is turning over if it is a mag???
 
Another consideration would be to check compression when spinning over with the starter.

Not ruling out the mag but a possibility that comes to mind.
 

A WD with 12 V and a Magneto.....

With that Voltage..it IS at idle speed before it even has a chance to fire..!!

Should fire right up, if it will run at all..!!

Are you real sure it has a Mag..??
