Lou, as all of my motors are for racing, I guess you can imagine how many times they are stripped for inspection and for modifications.
That O ring along with several gaskets gets used time after time.
The secret with the O ring is not to over tighten the carb to the insulator.
Over tightening tends to bow the carbs mating surface causeing an air leak in the O ring area which often gets blamed on the O ring itself.
The starter cable shouldn't be a problem from what I can remember of them.
It connects to the starter then drops between the starter and the motor.
It runs under the motor between the finning and is held in place by a thin metal clip that is secured to one of the bottom engine studs. It then comes up from the back of the motor to the battery. Easy peasy.
Sam.
