Skilled/experienced person to solder small areas on brass

I would like to meet up with someone who can clean up some solder repairs on some of my antique camping stoves, small in size. I'm not very good at soldering. Photo is one of my 100 year olds which have a poor designed air release screw, see the repair at the upper left. The top of the screw is the size of a pea so quite small, so these repairs can be delicate, heat sinks needed in all areas when making repairs. I use wet, rolled up pieces of a paper towel. I'm up by Quincy in Plumas County, very willing to drive somewhere within maybe 3 to 4 hours away, Sac is around 3 hours away. I have maybe four of this model and some younger ones that had repairs around the fuel bung. I'm retired, so any day works for me. Please PM me.

I called in to the radio station on their Swap Shop program, got one call from a retired Plumber, will see how it goes on Friday. He also collects lanterns, so maybe he will know what will work.
