Which direction equals less fuel clockwise or counter?

 

It should be labeled. I think Rich is clockwise and Lean is anticlockwise.

 

less fuel is clockwise

 

That's what I thought. Thanks

 

Oh, never mind, I was thinking FI.

 

Wait so when you turn the crew in clock wise as if you were trying to tighten it it's less fuel?

 

Yes, clockwise (toward firewall) less fuel. Make sure the carb has had time to warm up.

 

Ok cool thanks guys

 

You need a haynes manual or something...

 

its a fuel passage, so tighten the screw = smaller passage = less fuel

 

There used to be two screws. They eliminated the air adjust screw on later Nikkis, like yours, so that screw only adjusts fuel.

 

My engines a 79

 

Top screw on a 79 is idle airflow (open to increase air equals faster idle & leaner mix)

Bottom screw is fuel mix (close to decrease fuel equals leaner, but not as much effect on idle)

Joe, us SA owners always have to let people know we're dealing with an SA. Many engine-management details changed from 79 & 80 to 81.

 

My bad this is my first sa engine on account of the fact that I'm not a huge fan of the sa bodies but my 79 engine is in an 83 s model with an 85 gsl rear end

 

Oh, sorry I should have known that.

 

Not sure how you couldve known however when it comes to 1st gens you can't assume it has the engine it came with 20 somethin years ago either lol

 

"You built a time machine... in a FIRST GEN??"

Your car gets younger as it drives past!

 

Well to be honest that's how it was when I bought it from firebirdslayer666 but yeah pretty much

 

So do I still turn the top screw till it revs at 750 then turn the bottom one?

 

agreed. Not trying to be a dick but these questions have been asked over and over. Get a manual and spend some time on www.sterlingmetalworks.com The search button and archives are awesome too.
