Thanks Chuck for the info, but she did not want to start, but was trying I check my spark and it looks weak,this tractor has a magneito on it I put a new coil in it and still no help, new points, plugs, timing 5 deg points 17 deg. What can I do to heat up the spark to see if this will help, or move the timing alittle. Anyone have a suggestion.

Does this mag have a wire that runs to it from the key? What I'm getting at is Wico made a distributor that looked and worked like a type C magneto but it got it's power from the key, not the windings in the coil. The coil was located inside the "mag" housing but there was no impulse coupling so it didn't "snap" when it was rolled over. This coil could be weak. A lot of guys use these distributors and simply hook up an external coil thru a small hole drilled in the cap. It 'aint pretty but it works.

Did you replace the condensor?? Run a wire directly from the battery to the coil and see if this helps. You might have a poor power supply to the coil, or a ballast resistor.

I think you will find the early 50 did have a mag like the 'B'

The late B's had distributors (unless there was some kind of special order that would sub a mag for special use)

I would pull it off to get it running, then adjust the timing to get it running best, especially at slow idle. If, after that, it still won't start, I'd consider Spokkerd1 and Chuck's suggestions. Like Chuck, I've never known a 50 to have a mag.

get rid of the mag and get the delco distributor. Personally never heard of mag on a 50.

The magnetic field in the Mag is weak. It needs to be recharged. Points gap 0.015 on a mag
