The Huasheng clone of the GXH 50 cc Honda fires every stroke just
like a 2 stroke so they can use the same tach as a 2 stroke.
Same goes for the Robin Subaru 35 cc and the Honda GX 35 / 31 too
It is called waste firing and I know this is a very old thread.
I and many others really like the TTO tach.
