Default power adjustments?

hey guys. a friend of mine has just bought a 1st gen and was wondering if i could come down to his house and help him turn the pump up for him and i just wanted to go over it with you guys before it did. i was planning on

turning fuel pin to steepest slope
turning star wheel 2 turns
turn smoke screw in two turns

i heard there is things you could do with the power strew but you also have to adjust the idle screw. does anyone know what to do there exactly because working on someone else's truck, the last thing i want is something going wrong. let me know.

My truck has the 3200 gov spring and turned up. It runs like a scalded dog now! I can be at dead stop, floor it and roast tires and roll a little coal.
