Re: 76 CJ-5 questions.......
I dont see the CTO valve thingy...im guessing this has been tossed. After
closer inspection the "manifold vacum" does run to the distributor only and
the EGR valve it seems has nothing attatched to it.
I did have the gas tank vent hose loose in that picture.. its now back on.
The PCV valve is connected with a hose to a fitting right between the EGR
valve and the manifold..Im assuming pulling the gasses out of the valve
cover..as the rear of the valve cover has a hose from it running to the air
cleaner.
The fuel filter is out of sight on the other side where the fuel line comes
from the frame.
Does this sound any better? I now have a Haynes manual.. im trying to catch
up!!

Re: 76 CJ-5 questions.......
I had a brain fart on the vacuum lines yesterday. The EGR if hooked up
needs a ported vacuum signal, so does the canister.
'I' personally find a ported vacuum signal on my distributor gives me an
instant punch when I hit the gas, but stock most distributors came with
a manifold vacuum or a dual vacuum. The manifold vacuum on them makes
the emissions different at idle. You might want to play with that to
see which one makes it run best. The ported vacuum nipple is usually up
high on the valve cover side and only gets vacuum when the gas pedal
opens.
Can you explain where the line that was off at the top of the carb runs
to?
The line from the rear of the valve cover to the air intake is the
intake for the PCV system. Filtered air is sucked into the engine at
the back as needed and pulled out the front via the PCV valve that is
hooked up below the carb. That is also the same vacuum port the brakes
would use if you had power brakes.
How is the distributor cap and rotor?
If the EGR isn't hooked up, it isn't likely the cause of the sputter,
but as someone else mentioned it can be plated off. Actually is it even
hooked up to anything at the bottom??? You have headers and lots of
those don't make any provision for the exhaust part of the EGR valve so
it could just be in limbo.
If the EGR is indeed not connected into the exhaust, then it should be
removed and a metal plate put under it or in place of it. If it is
leaky, it can cause sputtering issues.
Do you have any vacuum lines or parts in the air filter?

instant punch when I hit the gas, but stock most distributors came with
a manifold vacuum or a dual vacuum. The manifold vacuum on them makes
the emissions different at idle. You might want to play with that to
see which one makes it run best. The ported vacuum nipple is usually up
high on the valve cover side and only gets vacuum when the gas pedal
opens.
Can you explain where the line that was off at the top of the carb runs
to?
The line from the rear of the valve cover to the air intake is the
intake for the PCV system. Filtered air is sucked into the engine at
the back as needed and pulled out the front via the PCV valve that is
hooked up below the carb. That is also the same vacuum port the brakes
would use if you had power brakes.
How is the distributor cap and rotor?
If the EGR isn't hooked up, it isn't likely the cause of the sputter,
but as someone else mentioned it can be plated off. Actually is it even
hooked up to anything at the bottom??? You have headers and lots of
those don't make any provision for the exhaust part of the EGR valve so
it could just be in limbo.
If the EGR is indeed not connected into the exhaust, then it should be
removed and a metal plate put under it or in place of it. If it is
leaky, it can cause sputtering issues.
Do you have any vacuum lines or parts in the air filter?

Yes, I am guessing that is why there is no vacuum line going to it.

Just in case you aren't quite sure what you are looking for: The EGR CTO
should be low on the driver's side of the block, between cyl 2 and cyl
3. It looks like a brass pipe fitting with a plastic piece moulded into
it. The plastic piece should have three vacuum ports set at right
angles. Originally there should probably have been a second CTO for the
ignition vacuum system located between cyl 4 and cyl 5.
