Honda Outboard BF15a Carb Removal - Stalling at idle

Автокөліктер мен көлік құралдары

A quick video that is hopefully useful to any owners of a small outboard that is stalling at idle. A walk through of the process for removal of the carburettor for cleaning. This issue is commonly caused by gumming up of the carb especially where it has sat with old fuel for the winter.
Whilst ultrasonic cleaning is said to be the best method for a thorough clean I have found removal and a good working over with carb cleaner is enough to get things running again.

    You took out the emulsion tube but still left the jet installed (its on the side of the tube below the screw you removed). Most issues with idle and stalling on these units is in the air bypass circuit, so the pilot screw and spring require removal and air bypass circuit cleaned. Once clean reinstall and screw pilot in till it bottoms out then back off 2 1/8 turns.

    Thanks @thedoctor8381. Will add a note to that effect to the description. These are complex little carbs versus something like an SU on a classic car and there seems to be little info online. But a total stripdown and clean certainly seems to make the difference.

    Hi @gregroth4969. No problem. Yes it should only take 15mins to whip it off and check it over. Good luck!

    Good luck 👍 also just a reminder that fresh fuel and filter easiest to check before whipping off the carb. E10 fuel can also degrade fuel lines which doesn't help 😊

    When you took the jet screw out I don't see a needle in mind I can take the jet out but I don't see a needle

    Thanks! I'll this cleaning to fix a no start, it only fires on starting fluid. I blame the stupid E10 petrol.

    Yeah it's pretty easy to take apart so worth a shot. You could be onto something re. E10. Am convinced not running as well since that change and car also gets about 10% worse mpg.

    Hello. I have a 15hp honda 4stroke Outboard . It is old looks like the one on the video. I need the condenser for it. I have looked all over for it and cant find it. Do you know the part number by any chance or where i can get it? Thanks

    Hey Armando. I haven't been down to the boat to check my engine but I don't think has a condensor as its electronic ignition. This pdf has wiring diagram which might help you identify. engine-manual.com/en/index.php?controller=attachment&id_attachment=104

    Disaster 😬 a good soak in penetrating oil and a try with a small stud extractor might shift it. Otherwise it's a careful drill the head off I expect.

    Next time use a JIS screwdriver.
