Can someone tell me the correct EMS setting for a 9 cylinder radial engine? It was on one, I see 1.5 for 6 cylinder engines but I can’t find any info for 9 cylinder radial with geared reduction.
thanks
It depend on the ignition source. You need to work out how many pulses per complete combustion cycles of all cylinders and divide by two, because the number of revs of a 4 stroke engine is two per suck squeeze bang blow.
