Well, got one done anyway. Took much longer to do than anticipated.
I cut some of that blue spring steel I ordered for making the carb springs. The first stuff I ordered was too thick for the carb springs and it finally found a purpose. Sliced a long thin piece off then heated and bent the edge of it into a circle to fit in the dogleg hole. Drilled out the old stuff. Put the new spring in place then dropped solder in. The bubble of solder was big so I also hammered it so it would stay very tight. Filed off the remainder and cut the spring to length. Seems to work well. UGH, only 7 more to go!
I like that gun bluing stuff so I'll probably clean them all up and coat them with that too.
