Decarboning the engine will not clean the carbs if they need it. There is no juice that will clean a carb without first disassembling it. And you don't want to burn an automotive type carb cleaner thru your outboard. Dirt in a carb has to be removed manually. Gum/varnish, use a carb cleaner and small jet brushes to clean the jets and passage ways.MISTYLADY2 said:Hello
You should have a connection on your motor that you can hook up a can of decarb to. It looks like a Valve stem.
If my memory serves me right you release while the engine is running, one blast for each cylinder then give it another longer blast. Shut the motor off and wait about 2 hours, then fire her up at a fast idle. Or better yet do this procedure in the water.
