spark plug timing

[wh cc guy]

Am I correct in thinking that both plugs fire at the same time?

I believe the answer is yes if the engine is a twin. What tractor and engine?

1980 782 kohler twin 17 series 1.

Yes, both plugs fire simultaneously on both the Kohler and Onan opposed twins. This is known as a wasted spark ignition system.

Thanks. I thought it worked that way. I guess that is the reason for the 2 out coil.
