[Fot] Spitfire misfire

[William Collins]

Joe Hovey, with me helping, rebuilt the engine on the #8 before the Mitty.
When we fired it up for the first time, it had the same misfire you describe.
We went through all the steps you have, and when nothing worked, Joe popped
off the Pertronix cap and put a new blue rotor in.    It fired right up and
ran on all four like a dream.     Old rotor looked fine...   ?

Blue spare  is in the track box and got one for the Dr.
