I recently read a trouble-shooting guide on another site that by swapping the two wires from the boyer trigger plate you can retard the timing by about 50 degrees. I am somewhat confused by this since my understanding of this system is that both plugs fire simultaneously every 360 degrees of crankshaft rotation (180 degrees of camshaft rotation), with the cylinder on the exhaust stroke being subjected to a lost or wasted spark. Thus, surely if you swap the wires around the plugs will still fire in exactly the same place as they always have? This is more than a thoeretical question since I attempted to time a recently-finished restoration project with the static view-the-dot-through-the-hole method and could not get the beast running until I tried an arbitrary and rather large amount of advance after which it started and ran sweetly. I have yet to try the final timing with a strobe and may swap the wires to see if this indeed changes the timing. has anyone else had this experience?
