Ken,
Are you sure the problem is no spark on 1 and 2? Generally when an engine
runs on 2 cylinders (1 and 2 or 3 and 4) it is a carb problem.
If you have an inductive timing light try connecting it to each of the
spark plug wires. If it does not show a flash on wires 1 and 2, you have a
distributor problem. If it does flash, you have a spark plug problem, or
carb problem.
There should not be continuity between the spark plug wire and the the
coil wire. There should be continuity, however from the spark plug wire
to the contact inside the distributor cap. Is it possible that you have
the wires from plug 1 and 2 crossed? That would have the plugs firing
between the exhaust and compression stroke, when there is nothing to
ignite.
Good luck,
Peace,
Pat
