I’ve got a 1970 1F and stock carb (rebuilt 4-ish years ago by Jim C I’m told). Installed a Pertronix II and Flamethrower coil a little over a year ago. Starts right up and runs great, the exhaust smells way less rich than it did with the stock ignition.
I just pulled the plugs to check things and cylinders 2-5 look a little lean/white. Cylinders 1 & 6 had a nice caramel color and no fouling.
Timing set around 12ish deg advanced (harbor freight timing light dialed to +5ish). No manifold leaks that I can detect, a little soot by the exhaust ports on 2+3. I sprayed brake clean while it was running around the manifold and base of the carb and had no change in idle.
Is this anything to worry about? Do I need to change to richer jets or do anything to fatten the mix? Anyone else with an electronic ignition have this? Thanks for the help.
Edit: Forgot to mention I capped the vac retard, so running with only mechanical advance.
