T16 running problems

[Lynn Eades]

If the rotor is loose on the shaft, and has turned in relation to the shaft, the arm contact will not be lining up correctly when the spark occurs. this means the voltage has to go higher to jump the gaps at the cap/rotor, and also the plug gap. this increases the load at the coil and the likelyhood of it failing to fire.
Just for the record there are two types of insulators that the plug leads plug into (one each side of the distributor, and two types of rotors (early and late) (as you now have correct T16 rotors you have eliminated that part)
I don't know enough about what wrong parts will fit in, so don't know if this might be a problem.
(I think there are two rotors that can fit in the crab as well) (one right and one wrong of course)
