<VV> Testing High RPM Drop-Out

[Jim Bannister]

I just replaced my Pertronix module for this exact problem.  It started as
misfire like you describe, and got progressively worse.  It'd run good for
about 20 minutes and then suffer crapoutitis.

Any suggestions for how to test what is causing my 62 Spyder to experience
serious drop-out (ignition missing) above 3500 RPM
