Michael -

Are you using solid wire or graphite core spark plug
wires?  If you are using graphite wires, that can be
the source of your weak spark problem (you get a miss
under the conditions you are talking about if you have
weak spark).  Also... is your coil new or very old? 
Is your engine properly grounded?  Are you using
points and condensor or Pertronix system?  If it's a
pertronix system, how old is it?  Answer these
questions and then we can better diagnose.

Alan
