    Anyone know the correct PLASTIC float bowl height for Weber 45 DCOE carb or where to get the info ?

    I think my floats are flooding my carbs cause when i try to start it up if i touch the gas at all it kills all chances & when i do get it running i see a lot of fuel in my V-stacks almost dripping out. + can't get to idle

    the measurements are 12mm when touching the needle and seat, and 26mm when hanging. you measure with the gasket in place

    when you pull off the cover that the floats are atttached to, you measure from the cover (with the gasket in place ) to the bottom of your floats.

    26mm hanging

    I take it the 12mm is when you adjust when holding the top vertical

    actually, you want to hold it horizontally against your forehead and if you cannot touch it with your tongue, then, it needs to be adjusted.

    OK so while Adam & I last month was trying to tune my carbs ( unsuccessfully ) we notice the 1 carb really spitting out fuel in the V-stacks. Figured it would be the floats need adjusting. So today i was doing so & noticed something missing yet again.

    GOOD one with all parts


    BAD one missing parts


    Needle Valve or lack of. ( part # 79503.200 )


    This might just be the reason for to much fuel LMFAO

    BTW if anyone has this part sitting around LET ME KNOW i'll buy it
