your engine dies when you start to run it up and perhaps idles sporatically. I think i accidentally left ignition on for a couple of days. First flight was OK. but the next time it would not run up, kept dieing. Also think it was missing on idle. No way to check ignition voltage, but I think that it might have been low. does this make since. PS: this is an MVVS 1.60 Gasser.
