    Default 9.9 4-stroke Honda can't hold idle after 3-4 winters

    My 9.9 4-stroke Honda was revised some 3 years ago and worked beautifully since then.

    Now, just as every 3-4 years with most out-bords, it tends to stall when in idle (even if warm), which forces me to gear in at higher rpm.

    Obviously these little babies suffer from spending winters outside and being used a couple of times in summer, but I would appreciate your advice on what I could clean/adjust to avoid spending 200 bucks for nothing.

    Thanks in advance!

    This is classic of a carburetor that needs to be cleaned.-------Fuel sitting in the carburetor tends to plug up the tiny jets / passageways.------Fuel must always be run out when boat sits unused!!----Some folks on here have struggled with this and finally got the carburetor clean on the third try.---It is quite simple to do if you take your notes and work carefully.

    Superb!

    Thanks Raceone for this answer, it's very helpful.

    Apparently, there are some pretty good YouTube videos on that
