  • Idle Air jet -Thread Size
  • I need the exact major thread size for the Marvel-Schebler TSX-33 carburetor Idle Air Jet, p/n 9596 orifice and screw. I measure the OD of the screw and get .153" but my 8-32 tap seems to fall in so I don't think I got it right...

  • DOH!!!
  • Yep, I figured out I was measuring the Economizer Jet part, they look the same except the Idle Air jet is a little larger. 10-32 is correct -same as the Idle Air Mixture screw. Thanks...

  • I get 0.179 n an original screw, 0.183 on a brand new one. 10-32 screw fits in both the screw hole and the jet hole.
