My omc 2.3 cobra is stalling when I go to gun it to pull up a wakeboarder etc, anything ovewr like 3 mph it will die unless someone mess;s with the linkage on the carb until its gets going. I have replaced the fuel filter. The boat dies when idiling at 5 rpm, and now doesnt wanna crank unless someone is back there to mess with the carbs linkages. We noticed some rust near the bottom of the carb, and some water on it. So we replaced the fuel fuelter first hoping it would work, and drained the old gas and put new gas in. Seem to have started to run, and idle better out of water in a large bucket. Now the engine will not start or idle unless someone is pushing up and down on the carb linkages for it to start. If we try to gun it or move forward faster the engine will die unless someone keeps there hand back there on the carb, till it boat gets going. Once it gets to going we have no problems running all the way up to 45 MPH +. SO do you think this is a carb issue my friend adjusted a link to get 10 rpm and it idles now kinda, but I still think we need to rebuild the carb maybe. the carb is a Rochester 2 barrel part number 17086107, which i see they have rebuild kits for it. If it is a carb issue how hard is it to rebuild a carb? Is there any rebuild links or sets that come with instructions only kit ive seen is made by mallory marine, and im not sure if it come with rebuild instructions.
