With the reamers it's easy to go richer, but leaner needs a little solder in the hole and then you can go from there.
Taking a reamer to a carb - for me - would be a little heart pounding.
I have used reamers, not on a carb, before and I was always somewhat nervous about the outcome.
Soldering a carb's jet hole would be even more stressful for me!
My hats off to any "carb-modifying-guru" who can do that with success and that level of skill!!
