mike canter Question....

another 8973 question.....

when the retard function is used, how much is allowable before the rotor phasing becomes a problem ???

eg
msd 10 ignition , coupled to 8973 , locked distrubitor , .......

say 28 deg timing...... how much retardd , before rotor phasing in dizzy becomes a problem / misfire / no fire/./.....

thanks

With a "fat tip" rotor, not pointed. Set the leading edge to just arrive at the distributor terminal at your base timing, then continue to turn the engine until the trailing edge reaches the other side of terminal. This would be the max retard without any compromises.
