    951 carb help

    Cleaned the carb. Re assembled them.
    Installed and notice the "T" nipple at the top.

    It's a clean fitting that looks like hose has never touched. So I left it alone.

    Turn it over and fuel pumps out.

    There plastic discs in there that pump one way from each other. i would take a look at them around the seating circular area as they are "cut" by the body they are attached to. Many people, even my self have missed this and it causes all sorts of I DONT KNOW headaches. It will Run lean, or a lean run away or will start and run for a moment..

    for those of you finding this when stuck on some 951 carb issues....

    use some care..a few of the hose fittings on these carbs are plastic and will snap if you look at them sideways. Specially the accelerator pump

    always use new gaskets

    take care not to damage the little plastic pins that hold the gaskets in place, or suffer big time during reassembly.

    check everything twice, as I'm sure you know by now that the mounting of 951 carbs is another bit of monday morning hungover engineering

    oh yeah..the main fuel line feed is 5/16

    Thank you sir. I got it figured out. What stumped me was the fitting looked brand new. No marks or paint worn off.

    yeah, that plastic shows no marks at all..they have always looked new!..even 10+ years down the line

    I've had a bit of practice as of late. Three carbed 951's in a month..that's a new record for me.

    Oh yeah..all 1999 models to boot.

    They are not that bad to work on.
    I did a quick google search and I found a guy cut a Allen key to length and glued it into a socket. So that what I did. Worked like a charm.

    Worst thing was throttle cable. And chock springs. Lol

    I welded my 951 carb bolt tool up out of a 6mm hex key and 1/4 socket and then roughed it up so I could spin it out by hand.

    The skill part is finding the allen bolt in the blind. Don't take the chocke levers apart, you can get a 2mm allen key and loosen up the lock bolts and slide the choke out.

    Be cautious around the throttle cable..really expensive!
