    Replacing fuel line on trimmer... line from tank is 3/32ID X 3/16OD...
    I have some 1/8ID X 3/16OD on hand and am wondering if there is any reason that I would NOT want that slightly greater flow to the carb...? Was thinking that the carb would only take what it needs and this would actually ensure adequate flow... BUT...maybe not?

    It's a Walbro WT carb.

    Get the hose to stay on the carb will be your problem. If you can get it to stay and not leak you are OK. But remember if it does leak it could catch fire while you are using it. Not good, not good at all. Fuel hose is not that much. Try and get the right size if you can.
