Yes I am wondering the same. Even if that is the case I am sure that the engine manufacture has taken this all into account and thus change there timing to suit as they do.
Next thing as I've said a magneto has a multiple discharge on collapsing of the field. So there is more than one spark per firing across the plug gap.
Really it is not relevant as you cannot change from the settings that they provide.
Now next thing how do we check our mixture setting on a run. Is there a difference between tcm and a lyc ?
Cheers
