i have a mercury 200 20 h.p. serial#3881934 that i just bought.the carb was off of the motor when i got it.the numbers on the carb are 5193a1 ba2b 1364-4929. i'm not sure if it is the right one for the motor.the carb has a internal fuel pump,with two ports on manifold flange.the manifold only has one port.i know one port is for the pump.and the other is for the mixture setting.the motor has no fuel pump.it does have a bracket on shifter side of the motor that look's like something should be there.i have been able to find {even though the #'s do not match} the gaskets{i have not bought them} for the carb.and even though the kits come with the fuel pump parts the flange gasket's still only have one port hole like the manifold.what i'm i missing.is that just how it is or i'm i missing some part's, if so what. thank you all for your time.
