318 Running Richer w/ Carb Swap
Update from a timing session last night. Just for a baseline we set it at an initial timing of 5 degrees.
What we discovered:
The timing light was cutting out on Cylinder 1 while setting base timing.
We checked 2 and it was firing consistently and evenly so we swapped plugged wires between 1 and 2 and 1 still had misses and 2 was fine.
Cylinder 7 with the timing light clamped closer to the plug was missing like crazy, but moving the clamp closer to the dizzy produces a consistent pattern on the light.
We changed the rotor because the new rotor had a tweaked top contact (bent to one side) and 1 cleared up but 3,7 and 8 were still missing closer to plug, but fine up by the dizzy.
Somewhat separate but it appears the plugs were gapped to ~.060 when the last tune-up was done.
Next Step:
Re-gap spark plugs to a more manageable .035 or so
Buy a new coil as it is is the one constant between the two ignition systems and it was running rich before.
Maybe snag another cap just in case even though this one is new that it's not at fault. See rotor being new but wrong.
Double check gap between reluctor wheel and pickup, maybe purchase another if nothing above changes.
