    Default 1950 EL Main Nozzle Question

    I'm building an M-61 Linkert and I do not have the correct 27333-50 main nozzle. I do have several 27332-50, M-74B main nozzles. My question is, can I use the 74" main nozzle on a 61" carb without problems ? Everything else on the carb is correct for the M-61, venturi, fixed jet, etc.

    I should just wait for someone smart to answer these.

    For all we know, Craig,...

    It might run better.

    (Better highways and all.)

    I can't wait to hear your results!

    PS: With all due respect, Kitabel..
    Cutting a fresh nozzle is routine for some: Just need the specs and too much money.

    PPS: I think this M74 (no 'B') nozzle on the left might be "correct" maybe.
    Stupid Parts Book sez they're all the same.
    Needles be different.

    Kitabel; Thanks ! I didn't even think about the nozzle length sticking out of the thicker venturi.

    Cotten; If I get the correct nozzle, I may swap it out before I start it. Right now I'm fighting an oil leak behind the front tappet block. I put a quart of 60 wt. in the oil tank a few weeks ago to check the feed line at the pump. And I'll be d***ed if oil is gathering behind and in front of the front block. And I haven't even fired the S.O.B. up yet !!

    As far as I can guess, Craig,..

    All 1" Model nozzle spigots are the same length.

    But that's a dangerous guess.

    ....Cotten
    PS: Even a more dangerous guess might be that the adjacent cylinder base stud had been over-torqued to where it cracked the case to the oil gallery.
    Nevermind. Bad memories..... ... .. .

    Cotten; According to Palmer's book the nozzle you show on the left is the nozzle for the M-61. At least it matches his description.

    I found them in M74s, Craig.

    And 1" Model nozzle spigots are anything from thirtyseven sixtyfourths to nineteen thirtyseconds.

    Great info ! I'm going to leave the M-74B nozzle in the carb and see what happens.
    Thanks, Craig
