I have a 1971 Chrysler 55, I'm having trouble with 2 different things. First off I'm having trouble keeping the engine running upon start-up. It runs ok when the choke is kept on and when I let off the choke and try to idle down the motor it dies. There is a brass screw inside the front part of the carburetor, is it and idle/mixture screw? Also I am not sure if the engine is pumping water through itself. I have it sitting over a trash can with water in it filled about half way up the lower unit. I'm not sure where the water goes in or comes out.
