How do I find out if the nutter bypass is legal to do in my state (NC)?

    You can pretty much figure any variation from stock will be
illegal, unless it comes with a certificate like some headers, manifolds
and their injection. But if they don't know about it, than it will take
one heck of an installer that'll trace all these hidden wires, and
vacuum hoses, back to the disconnected computer, that's missing anyway.

It is not legal for a mechanic to alter the emissions on vehicles in
most places.

The disclaimer on the Nutter page says 'for off road use only'.

However, the 258's Ford emissions computer was a failed last gasp
attempt to get a carburetor to pass emissions everywhere coming at a
time when mechanics have forgotten how to tune a carb.

When it was new and everything was working perfect, it worked at a cost
of at least a 25% cut in power and mileage.

If you take the engine back to a pre 82 tune (no computer) and tune it
up, it will get sweet emissions numbers and you get that 25% power loss
back.

No one would ever get away with calling me a mechanic...

My point exactly....
;-)

Meanwhile, the 'nutter' just involves adding a couple new wires and
tuning up the engine like an 81.

It is easily reversible if you 'had' to.  You could just put crimp plugs
and sockets on the wires.

On my last emissions I passed, I got 15 ppm HC and 0.16 CO.  NOx isn't
tested for on a CJ up here so no Cat needed.

Oh, the big trick for doing that valve cover or any other part with RTV
silicone is to do something totally foolish and follow the directions on
the package....

It takes 24 hours for RTV to cure at 70 F.  If you put any liquid
against it or even breath on the sucker before 24 hours is up, it 'will'
leak.

As mentioned, I only have the two top center nuts holding mine on, my
head isn't tapped out for bolts.  No leaks.

I made sure to wait 24 hours.  RTV on both sides of gasket.

    I would be like a miracle to have that computer and it sensors
still working properly or repairable. Yank it!
