Something that you might want to check is the stud that the coil wire screws to on the side of the distributor may be grounding against the distributor body. I have a '50 also, and found that grease and oil had gotten against the side of the distributor and was grounding my coil wire.

Take it off and clean it well and inspect the insulator to make sure that there is not break.

Some things I have found on tractors that keeps the spark from getting to the plugs.
Bad coil.
Broken wire from the coil to the points
points not grounded. on one the inside plate that the points mount on got painted.
points were not touching at the contacts.
points burnt or dirty
points were not opening.
Rotor missing or bad
Distributor cap bad

we will assume you have a distributor and not a magneto. You should have a coil next to the distributor. one side of coil connects to the tractor frame. the other side goes to the battery terminal (or thru the toggle switch to the battery.) on the terminal that is not grounded to the frame. if you have "power to the distributor" i am assuming you mean the coil is hot. the coil wire (big black) goes to the center of the distributor. the 4 plug wires come off the radius of the distributor. put a spark plug in one of the wires and touch the plug to the engine block. crank the engine and look for a spark. if no spark, you need to remove the distributor cap and clean the points. this assumes the coil is good. you can put one spark plug in the coil wire to the distributor, and touch the power wire to the coil small terminal on an off and watch the spark plug spark. if it dont, the coil is bad, or not wired up right.
