Posts: 199 | Our motor runs with the choke off but dies when we idle. We can idle with the choke open. We have ran a couple cans of sea foam through it and ran it wide open for about 30min as well. | ||

Posts: 983 | sounds like might just need idle adjusted....maybe bumped up a bit like its getting starved for fuel a little | ||

Posts: 983 | I had crack in my ball and would still prime and start....I thought being a 4 stroke newer motor might be fuel injected but if its a carb it def needs cleaned....the ethanol in the fuel will chew up the rubber seals and they will then clog the carb have seen many times why you have to run good gas I only run premium and us Lucas stabil to remove ethanol from fuel and prob solved | ||

Posts: 772 Location: Delavan, WI | Might want to start with a tune up, new plugs and fuel filter can make a big difference sometimes, these are simple to do- low cost items that should be replaced every couple years anyways | ||

Posts: 270 Location: SE WISCONSIN | Same thing with my pro kicker this weekend 1/2 hour cleaning the carb and it's good as new. The low speed jet has some junk in it these motors have very small jets in the carburetor just take the carb off and run a small piece of wire through the jets followed by a good spray of carb cleaner.

Posts: 489 | Best tip on these kickers I've ever had is when you're done using it each time disconnect the fuel line and run it empty. These carbs hate the ethanol in our fuel. Also there is a small port on the side of the carb you can drill out, it tends to get gummed up. I've had this done on every 9.9 and my mechanic said he does it to all of the ones he works on without even asking bc the problem is so consistent. | ||

The brass thing on the side of the carburetor you are referring to is just a brass plug that cover the air mixture screw. It's covered due to EPA regulations you can get the plug out to adjust the mixture if necessary. But don't start drilling on that plug if you don't know what you are doing. | ||

After you get the carb cleaned make sure you know how to drain it during storage. Running the lines dry is the first step. Removing the screw on the lower end of the carb stem is the drain and should be removed to drain the final bit of fuel from the carb during storage. The smallest bit of fuel left in your carb during storage will turn to varnish and gum it up. | |||

I've had small amounts go bad even with stabilizers. If you store it for long periods drain the carb. Why take a chance. | |||
