I've found several tachs, but don't know how often the Huasheng sparks per revolution. Anybody know where to find this data, or know which tach would work with this engine? Thanks.

OK, thanks!
So is that how it always is, no matter the make or model?

That is for every 4 stroke ever made.

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.
