3rd channel in a .12 rigger

[Brian Sorgente]

Going off memory here Mark but I think it's 1/4"-32 (same as a standard glow plug) try screwing it into a head button to check.

I would think the thread would be metric as it is from OS. My third channel needle is under the header and the line to the carb comes out through the hull which mounts the valve Needle is one from Al Hobbs. Don't have a photo as boat is in storage unit but will get one later and add.
