Re: 1960 40 hp johnson rds22
Sounds like you've got it set too lean. Adjust the idle mix richer with the idle mix screw. The knob may need to come off. The float should be set so it's even with the bowl gasket surface of the carb when you hold it upside-down.<br /><br />With the high speed oriface out, you should be able to pump gas right through the fuel pump to the carb bowl and out the plug hole. What are you attempting?
