The carburetor on the Tecumseh HS-40 engine on my early 1970's Ariens snowblower got rebuilt today. No welch plugs, but new seals and jets all around, along with a new float needle.
The problem is that the new main jet is leaking a trickle of gas down the adjustable mixture screw. IIRC the old main jet also had this problem. The adjustable part is sealed with a little O-ring and a brass washer over the O-ring.
Does this sound more like a problem with the O-ring, or an issue with the new main jet?
