Stromberg passage plugs

Post by dmdeaton » Tue Apr 13, 2021 2:13 pm

Carb runs great on new engine start, but dribbling a little fuel from the passage screws. They were a little loose but don’t want to snug them in until I ask. Not tapered and nothing to seal on the lip. I am thinking a touch of pipe dope maybe.

I snugged them up a little more and I think the dribble stopped. I was being too careful and anal. 😳

DO NOT put pipe dope on them. Those are called grub screws. They tighten again the edge of the hole. Allen head screws have nothing to tighten against and need a washer. If you really think you need something on them a little swipe through Ivory soap is the best thing you can use.

I understand that but the burr needs to knocked down also or it doesn’t have a flat surface for the edge of the small collar on the screw to seat against and seal. I deburred the threaded hole surface and snugged it down and all is fine. The burr was keeping it from seating 100%.
