Without admitting addiction <g>, I currently have two of the three engines in the 17 series--the B and h&m.  Jin’s first 17 was designed with a simple needle-valve carburetor, pushrod-controlled exhaust valve and atmospheric intake valve.  Next was the 17B with a throttle-carb and pushrods controlling both the intake and exhaust.  The latest 17 jewel is a hit-and-miss.  As the vid shows, the h&m does nicely hit and miss.  The softer-spring/s mod common to the larger M90 engine should also slow down the 17, if that is a concern.  If you have a lathe, turning shoes for the flywheels should add enough weight to slow it down as well.

The 17’s have been easy starting and very reliable runners.
