Title: WANTED: Brodak Needle Valve Assemblies, Needles, Proper O-Ring Size For .40s
Post by: Dan McEntee on August 18, 2022, 03:15:50 PM
    The Brodak web site show "Out Of Stock" on Needle Valve Assemblies and needles for the B-40, but I will call to verify tomorrow. If any of you electric guys that have sworn off engines have a couple of each laying around, let me know. Also if anyone knows what the proper size is for the venturi O-ring, I would like to know. Taking apart a used engine might bit yield good used parts or correct sizes. Just working on some previously abused engines.
   Thanks in advance!

I guess you missed the edit he did after I posted. Anyway, the o-ring out of my B40 is black Buna-N, square in section and measures .042" thick, .395" ID, .525" OD. Probably supposed to be 1 x 10 x 13.5mm

Hope that helps,

     I guess you missed the part where I wasn't interested in a measurement from a used engine because they might not yield good parts or correct dimensions. O-rings tend to shrink and distort after being squished in place for any length of time.
  Type at you later,
