Engine Performance problem
1986 Toyota Corona 4 cyl Two Wheel Drive Automatic 187352 miles

my boys put a re conditioned motor and box in my car 2 weeks ago. The carby wasnt running smooth it was preignighting, stalling when stopping no pick up and very slugish.
can you tell me how to re adjust the screws so its running perfect again. Or can you tell me how to hook up my alligater clip taco to be able to see the readings of my carby. As where puzzled as I dont have a coil on my corona. Like my old car
