[Roadsters] Out Of Ideas

[fairlady at putermail.net]

Sorry my bad, I neglected to say. I checked the spark on each
cylinder, replaced all four
plugs. The the rotor is turning. I removed all four plugs and turned
the engine until the
rotor was pointing at each plug wire and checked the piston and each
seemed to be at the
top.
