See here:B&S 49-series (810cm3/49ci) - TiPi's conversion for aircraft use1,800 RPM is high for idle, is there something about the engine that would suggest it is not capable of idling lower? Sheesh my cub would take off with 1700RPM no problem, empty of course. Something under 1,000RPM would be better.
Might get the idle lower with prop mass, but risk it will quit if too low.
