Once timing is set, tighten down three IP nuts and install fuel lines. Make sure you fully understand the information and accept the consequences before making any use of it. A tutorial on the use of computer controlled stepping motors. For instance, for most rotary and Ford TFI engines, we prefer to set the Fixed Angle to 20. For details consult the factory. When you exceed the base output of the engine by a factor of 25-50% more you may start to hit reliability issues. I would think that in the context of GP tuned factory race motors, theoretical limits of rotary valve intake timing (both opening and closing) are appropriate to explore. This timing valve eliminates the need for a control valve or solenoid valve. It doesn't sound much going from 49cc to 60cc but it is more than a 20% increase in engine capacity. As I've mentioned before, I'm using the pre-Raduino version of the BITX40 to which I've added an Arduino nano/Si5351 tuning rig with a rotary encoder attached.
