The Ford Barn

After about a 6 month sleep with a tank full of corn gas with the recommended amount of Stabil, I tried to start the engine. It wouldn't start until I opened the gav to over a half turn. Then the engine roared to high speed and the only way I could slow it down was to close the gav. It acted like an accelerator and I was able to drive it that way for a short distance. When closing the valve to under 1/4 turn the engine would die. After the engine warmed up it would behave normally. It has continued to act the same way for some time now. The colder the weather the longer it takes for the engine to warm up and for things go to normal.
The car is an early RPU with a repro Zenith carb which I bought for it when they were selling for $95. I actually bought 2 of these, the other for my '28 roadster which isn't experiencing this problem. The only problems I've had with these is replacing the floats soon after the corn gas got here and damaged the solder in them and several times blowing them out when debris got in them.
I'd appreciate any suggestions on what to look for.
Thanks, Robert
