I'm putting my Nikkin back in the car and I have everything hooked up. Just need to know what goes here (circle in red). It is the large nipple on the passenger side on the carb.

BTW, not using the carb in the picture. It is just for reference purpose

 

That is the port for your cold start assist, if you have removed the CSA (the bottle over by the windshield washer fluid reservoir) you can just slip a cap over it. Otherwise reconnect the hose from the CSA.

 

Guess I was right, Thanks.

Now just need to figure out where the throttle cable goes.

 

There are two cable brackets. The top one is for the choke cable, the bottom is for the throttle. Make sure to leave a little bit of slack to ensure the carb returns to full idle when your not on the gas.

 

I have four cable, accelerator, cruise control, choke and warm start up assist. I have them figured out now though.

 

Oh yeah I forgot about those other two. It's been about 2 years or so since I've had more than a choke and throttle, and since the choke is no longer part of the carb (Sterling's don't have em) and I don't use the fast idle I'll be removing that cable so it will just be down to throttle.
