I got myself an NGH 9cc for experimenting.

I have read the thread up to page 30 and then skipped to the end. About the ignition advance, let me state that a 1$ microcontroller is very well able to measure the time between two pulses, calculate the rpm, and advance / retard the spark accordingly.

According to Brutus1967 the pressure sensing hole on the front of the carb is the cause of the oscillating idle rpm's. Is there any confirmation for this? Is the idle better when the prop is replaced with a disk?
