With electromic ignition, what should the gap on the spark plugs be set at for street driving ??
Same here.My plugs are gaped at .035 (with electronic ignition). Of coarse that doesn't necessarily mean it is correct.
That is exactly why I asked the question in post #10.Another thought is carbon build up on the pistons. If the car has low miles and has been started and idled on the choke a lot it might benefit from a nice dose of sea foam down the carb. Your neighbors will love you too!

If that's the case, there is no need for snake oils like SeaFoam (Naptha, Isopropyl Alcohol & Pale Oil). That crap will just foul your plugs. A glass of water with the vacuum hose run from the carb base run into it with the RPM brought up to 2000 RPM or so will do a nice job of decarbonizing the cylinders without fogging the neighborhood.

Pinging with 110 leaded fuel is a big problem and very hard on the engine. I would start by giving it 10-12 degrees of initial timing (set by turning the distributor) and adjusting the mechanical advance slots to give a total of 34 degree max for pump gas, 36 max for 110 or pump/110 mix. If you need help with the distributor setup we can walk you though it. Too much timing with hurt the engine and it's something that should be verified immediately.

FBO has them. I noticed with their plate it puts a bit of preload on the springs and delays the advance. You may need to experiment with differant springs. Setting up a distributor can be tedious and time consuming. But has a huge effect on how an engine runs.There is a place that makes Mechanical advance limiter plates. Pull the dist, then remove the reluctor and pick up. Then you take the clip out of the center on the top shaft, lift the rotor mount off of the main distributor shaft. This also is the piece with the slots in it. Then you drop the limiter plate in place, using the slots with the desired amount of mechanical advance. It has slots that will limit it to 12, 14, 16 or 18 degrees of advance. You usually want 38 degrees of total advance. So with the 18 degree slots aligned, you would start with 20 degrees initial. Then the other 18 would come in mechanically for a total of 38. Maybe someone here knows where to get them. I found the link to the guy who makes them here on a thread about distributors or advance curves.
