I got a kit for my 4 lb Carter. It has two approx 1/8 thick base gaskets and one approx 5/16 gasket. When I pulled the carb, the base gasket was about 1/16 thick. Is there any benefit to which gasket is used. I pulled the carb cause I couldn't get it leaner. My tail pipes smell like raw gas and are black and somewhat sooty. Thanks for any input.
