    Hey thanks Chuck. Moral support is always welcome.

    So I did try again. Rapped on the bowls and that sorted #2 but #1 still peeing and now #3 is as well.

    I did come across something interesting on Youtube that I will try tomorrow. They advocate polishing the float valve seats to get a better seal. Basically, use a q-tip chucked up to a drill, add a dollop of metal polish and run it in the seat for a minute or so. apparently it will take care of any varnish or crud on the seat face. It can't hurt.

    I also will check float heights. I am sure they are ok but I might as well be really thorough at this point. I'm wondering too if I should bring the airmixture screws back to 2 full turns out.

    Well hang in there my friend. Hopefully I will soon be able to report success.

    Cheers man.

        recheck the gaskets arent rubbing against the floats while youre back in there. In fact, trim them back to the inner edge of the carb body regardless of if you think they are or not..eliminate that outright by trimming them.

        1 and 2 were pizzzing fuel and 3 wasnt. Then you tap on the bowls..1 stops..2 continues..and 3 joins in. Damned if that doesnt sound like gaskets or floats hanging up to me. I mean think about it a second. WHY would 1 stop with a tap ( because the float got freed up ) and 3 start ( because the running bike used up fuel from the bowl and the float snagged going back up when trying to refill the bowl ). Does that make any sense to you??

        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.

            Yes Chuck it does and great minds think alike as I did just that this morning. These carbs actually have the rubber o-ring gasket but mine were shot and I haven't had time to get the real ones (local parts guy for these is 1 hour away out of town) so I fabbed up paper ones as a temp fix.

            I am just about to measure float height now and button them all up again for yet another test.

            I'll let you know how this goes.

            cheers.
