1 warm the car up 1st
2 make sure your battery is full
3 unhook coil wire
4 open carb full thottle
5 can either pull all the plugs or 1 at a time
6 note the reading after 2 cycles then get reading after 5 or 6
7 hope you have 145 psi reading and all closely read the same
What do you mean "can pul all the plugs or 1 at a time"? Take out the plugs too, or just the wires? Stop at 2 cycles and start over? Or pay attention during the ignition at 2 and stop at 5 or 6?
