Help needed with sb 318

My concern about the servicing of the carb was renewed after I found and went through this manual.....

Again, based on reputation alone, I have (or had) confidence in the guy who did the carb for me......but seeing how specific the service instructions are......can't say for sure it was done to that level. Perhaps guys who know can tell me how close to exactly right it has to be to work.

I would expect shades of gray......to get the absolute best out of a carb......so as to be able to smoke tires, etc........yes. But to rev, and pull a gently load without stalling?
