    Quick fix on leaking float valves.

    Recently, I had an intermittently stuck float needle with a '78 1000E. For a number of years, I would give it a whack when It would stick, but it got to where that didn't work any more. I tried removing the drain plug from the float bowl, and letting it flush a few times with on prime. It seemed to work.

    Friday, I came to Maine, and the #3 carb on the 1000G here was sticking. A few whacks didn't help. The same flushing seemed to work again.

    I agree that it isn't that hard to remove the carb bank, especially on the G, but this technique is super easy, and is worth trying, especially when the problem occurrs just when you want to go for a ride.

    I would look for things like the gasket swelling and thus interfering with the floats path of travel. And see if the springy tip on the needle has stopped being springy..thus allowing the needle to drop too far and jam itself against the float hinge.

    I would rather trust my bike to a "QUACK" that KNOWS how to fix it rather than a book worm that THINKS HE KNOWS how to fix it.

      that's a good one, 850' . EZ stuff to get goin' again is always worth knowing/ remembering. and gives a clue too when the day comes to fix it forever.

      giving the floats a "full drop" indicating as Chuck is saying to get past a ridge or whatever! ...less good than his idea, I was thinking it was dislodging crudola around needle or seat causing sticky (maybe if bowl is never empty, the needle never gets to fully leave the seat) but this or Water would be unlikely ? if it's always the same carb.

      On small outboards ,if nogo, after two or three pulls, I ALWAYS empty the bowls (back into the tank and they flash right up...I even made a purpose made system on Seagulls to not lose parts overboard, it's so common with them.( I figure volatiles evaporate out quick , leaving too much 2 stroke oil+ salt water).

        I went out a few weeks ago and started up the ATK. Gas started pouring out everywhere
        The Dellorto has one big nut holding the float bowl on, so I pulled that, flicked the floats up and down a few times, buttoned it up and it's been fine since. Same principle with more direct action

          As to a "more permanent fix", I'll let you know if the leak comes back. Sometimes flushing out a piece of crap is all that is needed.
