Thanks Beech
In my future YouTube video project is to integrate a li-ion battery powered tiny arduino micro-controller with Bluetooth and monitor the RPM on your mobile App. The Android App will also allows you to see if the engine has spark. I have started a prototype to measure RPM with arguing and write an Android app to read the information from the device. When time permits, this will be on YouTube. Also I will be uploading an experiment with three types of Poppet Valves and noting its RPM on different settings. You might be interested to see what I have found on the G4 carburetor body. Thanks.
