First one is mine. "my other car is a fish" is the only clue. LOL
If anyone has questions I'll try to answer.
When the charcoal bits start migrating, they make their way into the carb bowl and cause all sorts of semi-random havoc.
Those jeeps used an electric solenoid valve to seal off the carb bowl from the cannister while the engine was running. But when the valve stops sealing, the charcoal moves right on through.
