I found the crab, with external coil, easier to diagnose. The old saying, if it doesn't fire, it's usually spark or fuel. It is easy to take off the air filter to see if fuel is coming out using the accelerator pump. If there is no blue spark at the plugs, see if there is blue spark at the output of the coil. If so the problem is in the distributor mechanical rotor system; if not it is in the electrical system and it is a lot easier to change out the coil to see if the spark improves. Also, (and I say this in partial jest) since Henry went to this system, it must have been better to someone other than a restorer.
