I have just the truck to road test thing in.
I went out to the truck the other day and tried to start it and it fired with a single low battery. I also have a 6V alternator on it as well. It didn't run buy a few seconds, the carb flooded out again. Seems that the last fix didn't last that long. The temperature is now staying up a little so I am sure that has something to do with it.
