[Shop-talk] Firing order problems. (Solution)

[Steve Hammatt Mount Vernon WA USA]

OK, here's what we found out.  While all indications
pointed to the magneto going in the direction indicated,
instead it internally changes direction and does go in
the opposite direction (internally).  So, everything is
actually as it should be.  Plus, I did switch the wiring
to make it "correct" and it wouldn't fire.  So, actually
the problem was only imagined.

Thanks!

Re-arrange the plug wires for 1-3-4-2 and see if it runs better...!

Are you certain you are observing the distributor's rotor rotation
correctly? If the wires are correctly installed (1-3-4-2) but you count them
'backwards' you'll get 1-2-4-3.

                        1
                    2      3
                        4
