I suspect that when the tank is filled any sediment or debris around the ta=
nk intake is redistributed thru the fuel then it settles again.  Classic si=

Thanks to all who have obviously given this misfire issue considerable thou=
ght. I will be sure to check all suggestions.
I  should like to point out however that it is the immediate vanishing of t=
he misfire after filling the fuel tank that has me confused.
This has happened three times simce the problem appeared.
I just don't understand how an ignition problem could change as a result of=
 filling the tank.
Furthermore I'm convinced that this is not a fuel starvation problem becaus=
e the amount of engine power being used has no effect.
Totally baffled.
Thanks again to all ... I'll  report back.

Hi John -

Yes, that was the point I was trying to make, sorry if it fell through bad =
interpretation!  As Ed McMahon used to say, "You Are Correct Sir!"

Cheers,

Coils can fail with heat and then recover when cooled. I had one that had t=

Given this I'd check (as a priority):

  *   Battery Master (when these fail they will ground the coil)
  *   primary ignition wire (white) from the switch to coil (cycle the conn=

  *   motor ground straps (cycle the connections)
  *   loose wires in the dizzy
  *   loose ignition wires into the dizzy or spark plug
Other things to possibly do (as secondary):

  *   replace rotor
  *   replace dizzy cap
I don't think it would be contacts or condensor simply because this would e=
ither be very regular all the time, or maybe sensitive to temp.

Best,

Alan

It is (or should be). If the battery switch is in the 'OFF' position it gro=

Hi Michael -

Have you tried cycling the connections on the white wire from the ignition =
switch to the coil, and also from the coil to the distributor.

You might also want to try disconnecting the black and white wire at the co=
