we have the 13b mounted with the 12a front casing and everything the motor is all wired up and waiting for the carb to come in. now the oil metering pump on the motor used to plug into the old carb setup where do i direct it now that the manifold doesnt have the holes for the oil metering hoses to go??need to know soon.

Premix, tap the intake or run line into the carb. Simple.

run the lines to the carbie.
