Check the point gap. Should be 0.020 inch.

Check the timing. Points should just open when timing pin inserted in notch in timing gear and spark lever up.

Change the condensor.

Check sparks at plugs by arranging brass leads so that they are about 1/4 inch from terminal on top of plugs and turn engine over by hand with ignition on. Make sure ignition lever is fully retarded when you do this.

Gap at the end of the distributor rotor should be about 0.025 for all pins in distributor body. Carefully bend brass tip to get proper gap.

Make sure rotor and cap are good. Also distributor housing. If in doubt, replace.

Make sure high tension wire from distributor to coil is inserted all the way.

Make sure points are clean. When closed there should be zero volts at the movable point. Also the ammeter should read about 10 amps discharge when points are closed.

Coil may be bad, replace it if in doubt. Borrow one if possible to test. Don/t leave the ignition on for more than 30 seconds without engine running or coil may become damaged.
