So I seemed to have somewhat of a miss driving at night . The speedster has a distributor with the Bosch head , It has a ground wire from the distributor to the block. Brand new wire core plug wires and new champion X plugs set at .032 .
The battery read 6.3 volts with or without the lights on. The battery is 1-1/2 years old , not low on fluid , good clean cables , new wiring through out the whole car wired to Ron's diagram.

The generator was charging at 4 amps but with the headlights on , it would drop way into the discharge side . I upped the generator to 7 amps charge at about 20 MPH, and now with the lights on it only dips to Minus 2 amps , and I seem to have no more missing . Any comment ????

All sounds normal but of course unless you have a voltage regulator on your car rather than a cutout - you will be overcharging your battery during daytime driving by a substantial amount. Wasn't sure about when you did the 6.3V test - was that before or after you advanced the third brush setting?

Before I adjusted it , it was 6.3 volts. .... I will get one of your voltage regulators as money allows: right now I'm a bit short on cash and need to get another tire for a spare for a rim I purchased, then I can put my other spare back on the top of my camp trailer. I was pleasantly surprised how clean the inside of the generator was . I tend to drive with lights on even in my 2000 Ford F150, a habit I picked up working for the Fire Department : it's actually Policy to drive with your lights on.

Lord knows how many people are driving blind out there....

Any theory on the rough running before I upped the generator ?

What kind of coil are you running? It may be improper coil or voltage sensitive and not producing properly at the slightly lower voltage you had before upping the generator output.

Obviously you accomplished something and my feeling is the coil too. Does your 6vt. coil have an internal resistor? Internal or external the resistor cuts voltage to the points to retard wear/pitting sending full voltage through until it heats up and the resistance value increases. If you noticed that it ran slightly better when cold this could be your answer.

Old man's fix. Run your lights in the day time. It's safer and all will be well.

ive had the same problem, ive got pretty much the same set up dist and everything, if you arent charging enough you will start running rough and miss firing.

adjust your generator to charge a couple amps with the lights on and run with your lights on day or night.

Running at full output and with your lights on day and night with 2 amps more than your lights and a distributor too will result in a short life for your generator since that is a lot of wasted power with generator running beyond its maximum output and all the time. I think you should rethink that since generators are worth taking better care of.
