So ... to answer those questions asked, I recently just completed a
compression check and a leak-down test. all checked out good and numbers are
comparable to the last check in 2009. Like I mentioned, the plugs are new but
I will check and test the plug wires. And, for those that queried I test for
spark/misfire by removing the plug wire at the cap one at a time.
Engine is 1500 plus .030" over and milled .100". Carb is a single 45dcoe13
Thanks for the questions,

Subject: [Fot] Ignition Problem
I have a question concerning my ignition - it's a Mallory Dual Point
distributor with mechanical advance and a Crane FireBall Hi-Output Coil PS92
(?). All are in good condition and set according to my engine tune with
plugs. When testing for a misfire, pulling one plug wire at a time, I found
the following condition : if I pull the plug wire for number 1 or number 4
cylinders there is a very noticeable change in the engine's idle. If I pull
the plug wire for number 2 or number 3 cylinder there is little to no change
in the engine's idle. There is a spark there but not as big the spark at
number 1 and 4.
Serious diagnosis will be most appreciated, or at least a direction of where
to start looking.
