Anyone have this problem? I have reddish brown crystals in the float bowls on my 4100 carb. The car has been sitting, but only for three weeks or so without starting. Last time I started it, the carb flooded and gas trickled out the vent pipe. I tapped the side of carb with a screwdriver handle and it stopped flooding. So the float was stuck with these crystals. I took it apart and found these crystals In the bowl in front. When I touch them they turn to powder. Some say it is the fuel, but? I only use Sunoco 93 unleaded so far. No additives in fuel. Any thoughts???
