When ignitions fail, do they usually just quit producing spark or so they start producing weak spark leading to total failure?
My blue label Falkon seems to have a weak spark, not a bright blue spark like it should be. This was in the sunlight though, but shade was provided by my hand. Engine has been getting harder to start over the last several flying sessions. I had one flight today and it ran good during the flight. Couldn't get it restarted for a second flight. That's when I checked the spark. It's getting plenty of fuel, so that's ruled out. Went ahead and popped in a new set of plugs and still couldn't get it to pop. I put a new set in the last time I was out too.
