Need opinions on passing WA Emissions

I'm running rich and i'm looking for an alternative to putting (2) cats on (i have dual exhaust)

My info on my jeep is over there <----

If can go either route, rebuild carb, hotter spark plugs and wires, (already have HEI dist).

Or just slap on 2 cats and hope it covers up the unburnt fuel.

Open to all suggestions and help, if I can get away with doing less than $200 worth of work and pass emissions, and you suggested it, i'll buy you a membership

I'm in Lynnwood, if you wanna come look at my jeep and give me some suggestions.

ok Found out that my carter afb comp carb isn't opening in the rear butterflies.

does anyone have an adapter to mate a carter carb to an edelbrock manifold?

2 big holes in rear and 2 small in front, not all 4 same size.

Well I inserted a 1 inch adapter plate that is entirely open in the middle, since my edelbrock manifold is open as well.

Turned down both screws in the front and opened them up 2.25 turns.

Seems to run better but i'm having issues hitting the throttle under load, from a dead stop. Seems to sputter a bit.

I'm going to try and retard the timing and see if that helps out (the motor was almost fully warm when I did this)


Opinions are appreciated.

I think after I do a full tune up I should be able to pass emissions, the air and fuel mixture screws were almost 4 turns out each :

Ok just called local licensing office and they won't use the new address without ID from that address.

Can't get an ID with that address until I have mail delivered there. Seems like alot more work, haha.

Move?

I'm glad I don't live in one of those areas. That emissions crap is a crock.

Haha, both my wife and I live within 2 miles of our jobs. I dont think we'll move very far.

I've only had emissions in Houston and here in Seattle.

I lived in Oregon for 19 years and never had emissions

I'm contemplating putting the vehicle in my father's name so I can drive the damn thing .........

But I still need a mirror for the driver's side. Also it would need a VIN inspection in Oregon.

It sounds like you're on the right track with the idle mixture adjustments. It sounds like you are describing a tip-in hesitation that you created? Did it have the hesitation before you made the adjustments? How did you determine it was rich to start with? Did it fail your emissions test? If it is running rich and you put cats on it it will just destroy the cats. Under what conditions is it rich? Idle only? Cruising? On accel?
The ignition timing should just be set to spec for that engine (whatever it cam out of) and then tune from there.
Did your Jeep have a cat before the engine swap? I think they make meet the original emission levels of the vehicle, is that right?
Sorry for so many questions but if you try to answer them I can try to help you

The jeep had a cat, on the 6 cyl that was on it.

Has a ACCEL HEI Dist on it with Edelbrock manifold and Carter AFB Carb and 1 inch spacer.

Was rich at Cruising on first test, then it was rich on idling and cruising on second test (i didn't let it warm up much) Neither test did I drive it on highway for 30 minutes and it has old oil.

The testing says Jeep w/ Chevy 350 engine, haha .. I just have to 'pass' I won't get a waiver or anything since it's not original equipment.

They testing it as a 8 cyl motor.


Yah as I 'depress' the accelerator on load is when it starts to hesitate slightly.

It did not have the hesitation until it sat for the past 'month' without being driven. I was working on my other jeep.

I'm gonna try and put cheapo copper plugs because they burn super hot, that's why they dont last as long. Keep the same wires just to save on some cash. Change oil so no old gases shoot into the chamber.

Drive it and get it super hot on freeway and then test and hope it goes well

Seriously you might also retard the timing just before your test, that used to help in my "muscle car" days in CA. I used to block off the vacuum advance good for about 12*. Also I'm not that familier with the Carter spread bore but on afbs and holleys I also used to disconnect the linkage to the secondarys to get them to run leaner for the test.
