Thank You, Guys.
I think I have the gremlins out of the tune-up systems, but I had turned on both heater hose water valves, last winter, and the one hidden behind the heater will not shut off. I'll get'er beat into shape eventually.
The problem with the poor running engine was the power valve in the centre carb. I had blocked off the two secondary carb power valves but left the centre one stock. Well, a spring holds the valve open dumping in gas to the venturi, but if you have enough vacuum in the intake manifold, the vacuum will override the spring and shut the power valve. Then you will have the right amount of gas going into the venturi from other carb systems. If you have a racing cam, even a mild one, you might not have enough vacuum to shut the power valve, so your motor floods all of time.

Today I finally got the hidden water valve closed again and the heater back in its place and bolted down. What a horrible job! Who made this truck so 'user unfriendly', that rotten b ------- Oh wait----?

As I've said, my truck runs nicely, but it burns too much gas, I think. So, today I took apart an old power valve and cut two coils off of the spring so it should be weaker. Now, my lighter vacuum should be able to hold it shut. I haven't installed it yet.

I wouldn't worry about the gas MM, they make more every day.
