Hey guys, Some dumba$* mech. Screwed with my bypass screw what I want know is how I could set it back to stock. Hoping to see if you could tell me how many turns from rich I have to go. Right now its smoking like crazy and running very very rich. I'm 100% sure he messed with it because I painted it and it obviously tampered with.

 

The 280ZX FSM clearly explains how to adjust the AFM screw (which actually has little effect on the engine).

What color is the smoke? Have you checked the CHTS?

 

I searched and couldn't find much. The smoke didn't appear till I played with the screw. What's the cktp?

 

Black smoke.
