    Carb Question Suzuki GN125

    Hello,
    I was riding and I lost the screw on the bottom of my carburetor. The engine lost power and all the fuel started leaking out. I turned off the petcock and walked up and down the road for 20 minutes looking for the screw. I did not find it.

    My question is:

    Does this screw do anything more than just hold the fuel in? Can I just put anything in there to plug it? It's a Mikuni carb for a Suzuki GN125.

    Thanks

    You could try a woodscrew but will need to be really tight or it will leak.

    Yes it is a drainscrew only.

    Dont use a woodscrew.

    Also it must seal. Leaks are very real fire hazards.

    Consider carefully before applying liquid anything to seal it.
    Don't you look at my accountant.

    As already stated ... it is a drain screw. Holding fuel in IS important enough to have one there. The bike wont run well without it.

    It should be a metric size ... so they won't be rare or expensive to replace. Look around your own home (or take the bowel to a hardware shop).

    The lost screw will probably be about half a kilometer back from where you stopped. And now swept off the road by other traffic.
    When life throws you a curve ... Lean into it ...

    Thanks for the replies. Just to follow up. It is a custom Suzuki part. I read elsewhere that it is tapered and that is important as there is stuff inside the carb that can be damaged by just screwing any old screw in there. I ended up pushing her home and ordered the part which should be here in a couple of days.

    Cheers,
    Gardner
