Q-jet carb Gods, need adjustment pointers

[dukcaln]

Ok guys, eally starting to figure out this truck...Think the timimng issue is done and set, got the exhaust and header leak fixed, now I want to takle the carb adjustment..... let me first say it is the original 4b q-jet from 1972 and was recentley rebuilt when the motor and tranny got built (less a year ago and 750 miles)... using the stock manifold too.... any ways, I had a friend adjust it but I think he had no idea what he was doing. So here is what I know r have done..

checked the mixture screws by turning them in all the way... left side took 3 less turns to close than the right... So once I closed them i turned them out 2 1/2 turns and fired the truck up....idles and sounds great.. took it for a ride just around the block cause it got dark but seems good.... thats all I did so far...

So tomorrow how do i go about dialing it in with out a vacuum tool. I was told to turn the screws in until motor starts to idle down then turn out until some thing happens. Once that is done then turn in 1 1/2 turns and that should be good....... is this right?

Or I thought since the scews are out equal turns (2 1/2) to drive it and keep turning out 1/2 turn until I find what runs best.....

so am I going in the right direction or can you guys steer me the right way.. really all comments and suggestions will be great... i am a rookie at this...
