Here's the rebuild kit. The design is slightly different to the Nikki's found on the FB.

You'll notice that it only has an idle fuel adjustment screw, and no air idle adjustment screw as found on the FB Nikki's.
There's also no idle up or emissions gear on it as this was not available/required in 1971.
The car runs well, but sometimes the idles dies on coasting. I'm not sure why at this point. If I put the choke on to raise the idle up to 1500rpm it idles fine.
Any thoughts?
