I have a 7.5 merc made in 1978. The carb sputters gas out of a port that sits next to the choke shutter. When the engine is run at low rpms it eventually kills the engine. I believe it is being flooded out. The engine runs great at higher rpms and when running at higher rpms does not have the gas coming out of the port.<br /><br />This same port will also shoot gas out of it when the motor is being primed. It does not happen a the first few times when you pump the ball, but when the primer buld is full. Any help would be wonderful. Thanks

Re: carb is leaking gas from choke valve

The inlet needle and seat are not being closed off by the float allowing the fuel to rise to too high a level in the float bowl. The carb needs to be removed, disassembled, soaked, all passages thoroughly cleaned blown out with compressed air and then a new kit installed. The kit includes the inlet needle and seat but does not include a float. Do not attempt to reuse the old gaskets, seals and parts as you will likely end up doing the job over again.
