Cleaning return - 44sbn

[jordanh]

i have a set of 44 sbn carbs that I purchased. The carbs are in relatively good shape. I am having
A hard time getting the return line port unplugged tho. I have tried a compressor with a rubber tipped air gun. Let them sit in Chem dip for 36 hrs, and now today put them in an ultra sonic cleaner. Nothing seems to work I can't get anything in the brass fitting because it's a 90deg fitting. Any ideas?


I've read about people drilling them out, running them both to a 'Y' fitting and running a jet in the return. Rather not go
This route tho.

A small drill bit just to push out the dirt? Not drill it out.

Man that's a tiny hole though. I'll have to check it with some gauge pins on Monday and try it with a drillbit from work. I do not have anything that small in my garage. I'm gonna try to use welding wire through the fitting and see if I can break anything free

Yeah they make a welding gauge out a tool to clean a torch that's a bunch if different seize wiree

I usually pull a wire from a wire brush and hold it with needle nose. Not the most advanced tool but it works.

Its hard to beat it if it works. cheap and a easy fix
