Okay.
here's the latest on my miss in my 26cc Brillelli with walbro carb.
I isolated each piece starting by running the battery straight to ignition, no switch or anything... still misses, so I didn't worry about any of the other components. It occurs to me that I should have switched batterys also at that point, just incase its a battery short between cells or in the wiring... I'll try that Sunday. BUT THE GOOD NEWS IS that I maidened the Jerry's Big Boy thursday, and Dang that plane flys nicely. Even with a miss the engine runs reliably and I really think that this plane will be one of my favorites. If I can't get this miss gone ( Sunday all the gasser guys will be at the field, and I'll let them twist some screws) I will buy a S&S ignition. Maybe a new sparkplug first and switch from the 25:1 mix to 40:1, since it's pretty well broken in.
