Yes you can do it without pulling the carb. Pull the tank :'( and you can get to it. Use the best fitting and newest screwdriver you can inside the carb. Most here replaced the bowl and diaphram screws with stainless allen heads.
Ok, cool. I really don't want to pull that carb again unless I absolutely must.
Honestly, I didn't have any problems with the stock screws, thankfully. I know what you're takling about, though -- the stock carb screws on the Triumphs are TERRIBLE. About as hard as warm butter. It was pretty much manditory to replace those, as the stock screws were destroyed in the process of removing them.
As far as the spacer -- okey doke. I don't have a micrometer, but I'll see what I can do. Has anyone tried to just get a replacement, or use metal needle shims?
Oh, and I'm in Reston, VA. You?
