odd thing

[BIG MIKE]

no get this i have a 34 flatehead set my plugs up on the dist as for a 42 flatehead the firing is the same thing for a 34 as well as a 42 , so why are the plug ends set differantly on the dist caps on both engines when the firing is the same?

Rotors must be different.

Study both pictures again. They are wired the same. Pay close attention to the cap notches.
