Response to Valve stem length

...is to control the amount of valve stem that is sticking up to be hit by the striker. That's basically how Sumatras control power; striker spring stays the same but the "power wheel" blocks the striker hit to the valve in varying degrees.


I tried using it with the QB by making several length valve stems but found my results to be harder to control than the other power mod methods. In the end, just made the Delrin valve stem to end up with the same length protruding from the valve head as a stock valve stem. Others may have had more patience and gotten better results.
