    Hello All. I need some help with my Husky SM610. I think the float valve is stuck and it`s leaking fuel in the engine and all the way trough the exhaust.
    It`s basically dripping gas at the lowest point of the exhaust, and only when it`s on the kickstand, if it`s standing upright, it doesn`t seem to leak any gas.
    Is this fixable by miself? Take the carb out and clean it? And what other steps would I need to tale?
    The engine oil might be contaminated also.

    Thank you!

    I have an 08 sm610 and it is fuel injected.
    Mine leaks fuel from the breather pipe on the clutch lever side top of the tank when on the side stand.
    It is when the tank is full enough that when lent over on the stand the fuel level is higher than the breather.
    The pipe ends just below the headers.

    Ok. any tips on how to fix it? It leaked gas trough the entire engine and exhaust I think. Thanks

    I doubt it.
    A stuck float fills the sump with petrol
    I just go fill up before a run out, not after, so theres less fuel in the tank when its in my shed.
    I would like a screw on type fuel cap with breather, then i could block the one off on the front of the tank.
