how do i set the mixture on 1986 gl carbed

[vulgora]

i had it set just right 2 or 3 weeks ago , after i just turned it at random and turned down the idle (it was at 1k for along time)

 

and it had lots more power i could acually drive in 5th at only 45 mph with out dogging it out and loosing power also good vacuum right in the middle, before , (and now if in not going 55 or 60 in 4th then shift in 5 th and even then barley maintains power and vacuum in the just below middle .

 

so any tricks i cant figure out how to get it down

 

thanks !
