    Default Cleaning out gummed up 2 stroke carburetors?

    Anybody got a fix for the white crap that gums up jets and internals in a 2 stroke carb?

    I tried acetone, no fix. Don't have a ultrasonic cleaner anymore.
    Excuse me, I farted.

    DYKEM solvent, for removing layout blue.

    Pour in the carb, swish around for a minute and pour back out; stuff works like magic.

    Brake cleaner, non-chlorinated.

    Wear rubber gloves and do it outside.

    Default Mek

    If it were me, I'd try MEK (methyl ethyl ketone) sold in Lowes or elsewhere. A gallon goes a long way. WEAR nitrile gloves and don't breath the fumes. But FWIW, MEK was the main component of Gumout carb cleaner years ago before they changed the formulation. It worked very well but is one nasty chemical to get into your system so do the right thing

    I've had very good luck using denatured alcohol for cleaning out fuel tanks with *very* old gas in it. It takes a while but it will strip out all of the old varnish that has accumulated. It hasn't effected the plastic floats in the carbs either, other than to clean them. Can't say what it will do to the carb diaphrams though.

    David, brake cleaner is very good for cleaning out the muck and corrosion.
    However, remove any rubber seals, diaphragms and plastic parts before you use it, as the brake cleaner will kill these.
