Perhaps I am wrong but the spark plug firing twice as often may cause the "hour" meter to advance faster than at the lowest speed?
The reason for the hour meter is to better judge when an oil change is due? Yes? No? (maybe?).
That's why I got one that advances via the spark plug. At least I hope it does.... Heck I have NO idea. lol
Those hourmeters only sense the spark plug firing to know when the engine is running, then the hours increment based on a watch crystal, not the number of times the spark plug fired.
