I think the engine will start with a bad resistor,
but it quits once you release the starter switch.
These were used on speed boats too, they used a lot of auto engines in boats and those resistors cause starting problems.

I think you need to check your timing to make sure
that it is ok. You said you have a weak spark at the plugs, here's a procedure for checking
your ignition system,

1. Check for battery voltage at the coil. Use a test lite or volt meter.
2. Check for battery voltage at the points. Use a test lite or volt meter.
3. Remove distributor cap, rotor & points cover;
remove the coil wire from the distr cap & put within 1/4" of a good ground.
4. With points closed & ignition switch on, snap the points open a few times and watch for spark
at the coil wire end. Should be a hot spark.
5. If no spark is present: you may have dirty points, a bad condenser or a bad coil. Coil primary wire must be attached to - post on coil if battery is - grounded. If battery is + grounded then the primary coil wire must be attached to the + post on the coil. Hal
Make sure those points are set at .020" and run some 320 emery cloth through the points when closed. May have a coating on them.
