i personally think this is fuel related but for one second lets back up and look at spark.
i have 8.94 volts going to dist. i dont know how to test the hall effect to see if its dropping to 0 and all. but visual inspection shows al wires free of damage, cracks etc. the sensor itself is spotless, the brass colored cup with the the tabs in the dist is spotless an corrosion free. when running i get 12+volts at terminal on coil. but lets say spark is weak and not burning the fuel instead of the theory of too much fuel getting to engine
