Mariner 9.9 just dies

[fishfinger]

I have a 9,9 hp mariner,single carb ,the out board starts sounds like it is running on one cylinder,runs for a bit say a minute and then dies ,stine dead as if you cut the fuel supply off,it take a lot to start it again,definatley running on one cylinder.



I removed to carb to find that inside the motor there are 3 thin metal plates on either side, looking into the throat, the right hand side plate’s have a fine layer of rust just where they open and close, tried to clean it a bit but has made no difference to the engine, any idea’s what these plates do? My outboard is about 7 years old and has been in storage for 3 years ,I have cleaned the carb and the plugs both have spark.

The outboard has a total of about 15 hours of duty in it’s life.



Any help here would be great

Re: Mariner 9.9 just dies

Those thin metal plates are reed valves. The must seal properly for the motor to run properly. Should not be any rust on them. Here is a good starting point for you.
