factory carb settings?

I have a model 190432 Briggs and Stratton type 2707-01 code 84050410. I need to know the factory pre-set carb setting and how to adjust i.e. from close....out 1 & 1/2 turns and a view of the 3 set screws would be most helpful. I have tried the factory site and it was useless unless u want buy a new motor (i am web novice but a fair shade tree). My daughter brought me here because she says you all know where to find answers(duh dad... Please if you can HELP ME). I know she's an older motor but she ran like she came off the showroom floor until my dumbass put some questionable gas in her. I drained the fuel and replaced the plug( I even drained the bowl and thats when she had showed me her teeth...lol). I made adjustments to the gov and carb to try to get her to run smoother but to tell you the truth and i feel a bit embarassed i never turned the drain valve in(2 find out what she was set at) and that started my nightmare help please.I have not had any major mechanical issues and do regular routine maintenance on her every 6 month. I usually would just look at my manual but i don't have one for this unit.
