I made some progress today, some by some stroke of luck.
After lots of reading, it seams the old sleds with no regulator use high wattage light bulbs to absorb the excess created. What I knew but did not verify is that yes my lights work but they only work when the ignition switch is in place and on the run/lights setting. So when I was testing voltage, the ignition switch was off and I never paid attention to the lights as I don't see the taillight and the headlight points down when the hood is up. So.... with the engine running, lights on (taillight needed its contacts cleaned), the Evinrude gave 6 volts at 1500rpm idle and upwards of 18 volts when piss revved. Much better than the 30 but still a bit on the high side. I now realize I did not check to see if it was the bright or dim on when running. Either way, its on the right path.
Now for the Ghost. I ripped the carb off again, verified the float was slightly greater than parallel when inverted. I found the new O ring was too large and rolled off the recess where it sits when I stuffed in the discharge tube/main jet. I installed my other backup o ring and used an Xacto knife to carve it down to fit snug. I got it to fire and run on both cylinders a few times and rev a little bit. I then played with the hi/low needles and get it to rev a bit more. Then it just sprang to life. I think it had plenty of raw fuel to clear and needed some heat to do this. I removed the tools that were holding the exhaust pipes from the mufflers and it continued to run. I backed it out of the shed and listened to it idle (1500rpm) and how it revved. I played with the needles a bit more so that it wasn't loading up at idle and took it for a few spins in the yard. I leaned out the hi a bit as it was loading up under full throttle, not much but enough to clean it up some. I don't want to melt the pistons so final settings will be done when our bitter winter sets in. It restarted first pull of the recoil as well.
Its lights and rectifier work, was getting approx. 6 volts at idle and 15 when revved right up. Quite happy so far as it has some decent power when opened up. I will continue to run it a few times per week to ensure no further problems do not crop up prior to the cold.
So whats left on the list is to play around with the lighting, wiring (possibly getting a voltage regulator), get a fresh battery and ignition switch for the Evinrude. The Ghost needs a battery, plugs, reassembly of the exhaust, cowl bolts and a good cleaning.
