I bought a 2002 Yamaha 130 TRLA. It had about 10 hours on it. the previous owner (neighbore) said it still had break in oil in the tank. When I took it out it missed a few times. Changed out the plugs. it runs great at idle, and all throttle operations, except when full throttle out of the hole, it dies. slowly advancing the throttle is no problem. it doesn't miss after the plugs. i know it had sit for awhile. i filled the tank with fresh gas the day i purchased it.

Can a person use carb/choke cleaner in a oil injected engine? i am going to put 2+4 fuel additive in the tank and fill.. any suggestions or help? would appreciate it.. thanks.

dont cheat your motor, break down the carbs and clean with carb cleaner or soak overnight if you have the time.

THANKS FOR THE INFO. I DON'T HAVE THE SKILLS TO BREAK DOWN THE CARBS. I AM ABOUT 129 MILES (ONE WAY) TO PHX FOR ANY AUTHORIZED DEALER. IS A CARB KIT REQUIRED FOR THE BREAK DOWN? THERE IS TWO OUTBOARD MECHANICS IN THIS VERY SMALL COMMUNITY, BUT, THEY ALL UMMP AND HAA ABOUT YAMAHA MOTORS AND PARTS.. ANY IFO APPRECIATED.. THX

If you don't want to tear the carbs apart you can try a shock treatment of Berryman's Chemtool (Walmart) in the Racor fuel/water seperator filter that should be on your inner transom somewhere. It will disolve any gum or varnish in the bowls and hopefully clean out the main jets which is what I think your problem is. Once you get it cleaned out use a fuel stabilizer like Sta-Bil (Walmart) in the fuel tank to keep it from degrading. Carbed Yamahas have to be run once or twice a month to keep fuel in the bowls and prevent varnish buildup. Even if you're not using the boat its good to run the motor on the garden hose as frequently as you can.

Hamfisted, or anyone else that knows:
The boat/motor does not have a fuel/water seperator installed. Just a fuel filter by the pump. I just ordered a Racor B32013 from BoatersWorld. Can you explain the process of trying the "shock system" you mentioned.

no seperator=condensation/water in your carbs/motor etc,probobly the main cause of your issue. what ham means is unscrew the separator, fill it with the chems,replace and run the motor for a shock treatment. and dont be scared of thems carbs,they dont bite, only a few hand tools needed.

Just one question on the "shock treatment", a fuel/water seperator keeps the water from going back into the fuel line. How will it take the chem into the fuel line? Can one not just take off the Carb silencer and spray directly into the carbs at a 2500 rpm rev, or so? appreciate your thoughts..

Allan,
You could try a shock treatment with "Seafoam" to clean up those carbs:
3/4 gallon fuel
3 oz TCW-3 oil
16 oz can Seafoam
Mix above in small contailner (I use 5 quart jug that my Mobil 1 comes in). Disconnect fuel line at bulb (from tank) and connect short piece of fuel line to bulb to go down into small container.
Run motor on driveway with earmuffs and garden hose. Motor is gonna smoke pretty bad - best to do this when wife is away shopping or something - wives don't understand things like this.
Run the motor for fif**** minutes at fast idle - turn off and let set for fif**** minutes. Do again for fif**** minutes and let set. Repeat until fuel is used up.
Now, hook bulb back up to main fuel line and run for fif**** minutes to get all of the concentrated Seafoam out of the system.
If this doesn't do the trick - then I would try removing the jets of the carbs (take note how many turns they are set at now) and squirting Berryman's Chemtool directly into the seats to clean out any possible varnish/gum.
Good luck,
Ken K

Ken,
i just recieved my "seafoam". Reference your recommendation for the "shock treatment", you recommend:
3/4 gal. gas
3 oz. TCW-3 oil
16 oz can of Seafoam
My 2002 130 Yamaha is oil injected. Do you still recommend I put 3 oz. of TCW-3 oil in the mixture, if it is oil injected.

Allan,
I would drop down to 2 oz of oil on a motor that is oil injected. You will be doing the shock treatment at a little above idle, and at that rpm the oil pump will be delivering something like 1/75 oil/gas ratio. Seafoam is a strong detergent, and can "wash down" the cylinder walls pretty fast - you need the extra oil in the shock treatment mixture.
Good luck,
Ken K
