98 Yamaha L200TXRV Float Sticking?

[Justdocked]

While I was rebuilding my home post hurricanes Frances and Jean, one of my twins has developed a problem. I did the unthinkable and neglected them completely for over a year. One was just happy to see me and fresh fuel, the other has the center carb spewing gas as it runs. Took off the air cleaner element and it seems to flow out of an orifice above the venturries(sp?). Was wondering where I would find an exploded diagram/manual, or should I just whack it with a hammer and hope it frees. Just kidding, but is there a way to clean or spray out the float bowl with the carb still installed.
Thanks,
Ed

If you can get your hands on some Amsoil Power Foam that's the best for cleaning out the bowls. You just remove the main jet from the bottom of each fuel bowl and spray it up in there and it foams up and flushes everything out. Second choice would be Berryman's Chemtool spray (Walmart), but it doesn't foam up so it takes more work. Good luck.

Mike,
Thank you for you assistance. Free at last, free at last. Yes indeed, the float's free at last.
I had an old can of a defunct manufacturer's foaming fuel system cleaner that was designed to be injected into the carb system via a schrader valve. It cleared up the problem pronto by shooting it into the float bowl as you suggested and it foamed out the top. Outboard idles at 700rpm steady.
I sure wish the memory on my account had been adequate for the file. Alas, I am on dialup with a 250 MB limit.
Thanks Again,
-Ed

Ed,
You might consider a shock treatment with SeaFoam or RingFree to help clean out the rest of the carbs and fuel system.
If not a shock treatment, then definitely start using SeaFoam or RingFree in the fuel.

Any suggestions for the best way to get the Seafom into the carbureted Yamaha 200's cylinders? Obviously since it's horizotally aspirated the throttle body throat doesn't work.
Here are the directions...
With engine warm, slowly pour 1/3 to 1/2 pint through carburetor or throttle body throat. (If vehicle is port injected slowly pour SEA FOAM through direct manifold vacuum line that will feed all cylinders, possible sources are P.C.V. valve or brake booster line.) This will pull SEA FOAM down on top of the pistons and to the back of the intake valves to dissolve carbon.

Ed,
This is from a previous post of mine - the shock treatment will de-carbonize your motor and clean the fuel system from the primer bulb thru the carbs:

Two strokes build up a lot of carbon internally and need to be de-carbonized by doing a "shock treatment" with a detergent like Seafoam.
I like to do the shock treatment once a year on my C115 - in late winter when I am going thru my list of "spring make-ready".
If you use a detergent like Yamaha Ring Free or SeaFoam all the time in your fuel tank, then the carbon buildup is not as bad. Still, a lot of 2-stroke owners will de-carbonize once a year - you will get various opinions on this.
I "shock-treat" my C115 by running the following mixture thru it. This will smoke up the area pretty good, and leave a lot of carbon on the drive way:
16 oz can Seafoam
3/4 gal gas
3 oz oil (2 if oil injected)
Disconnect the fuel line at the input to the bulb and attach a three foot piece of fuel line to the bulb. Mix the above in a small container -
I use an empty 5 quart oil jug. Set the container on the deck of your boat and insert the fuel line and secure to make sure the end stays on the bottom of the container. Pump up bulb and start outboard with earmuffs and water hose, of course -run a little above idle for 15 minutes and turn off. Let sit for 15 minutes. Run again for 15 minutes. Let sit 15 minutes. Repeat until all mixture is consumed. Reattach main tank hose to bulb and run regular fuel/mixture thru motor for 10 minutes - you want to get the concentrated detergent out of the fuel system.
Now, clean up the drive way before your wife sees all that nasty carbon and makes you get rid of your boat.

Thanks Ken. Worked like a charm!
