Thanks to all that replied. My carb had been working fine, considering the truck hadn't ran in ten years. i first fired it up with a little shot of gas in the air filter and a gallon of prestone antifreeze served as my gas tank while i removed and inspected the original gas tank. The tank was surprisingly clean. But the second time I fired it up, the floats were stuck on the Zenith carb and the engine ran rough. I opened it up and it too was surprisingly clean, but by that time the gasket was a goner. I made my own yesterday and will try it today.
