You're pretty close, and as SS said, your (likely) original Cat is probably not doing sh*t. The new Magnaflows are supposedly "3-phase" meaning they will reduce HC, CO, and Nox.
Point being... a new CA-compliant cat would likely get you through.
Not that you shouldn't tune it up.
When I got a new cat, I went to a random exhaust shop and just made sure the guy kept the thermo sensor intact and in place. I think I paid $60 cash. Not including the cat, which I ordered online. A million vendors sell them, and they're all the same price. The cheaper 49-state version is pretty much the same as the CA version, but nobody will ship the 49-state version to CA. And you can fail if a very anal smog tech checks for the "CA-compliant" stamp and doesn't find it.

I had my rig tested in Los Angeles a few months ago and the guy crawled and checked the number embossed on the CAT. He said they're required to make sure the CAT is CARB compliant now, or if they get caught not checking by a spot-check weasel they can lose their license.
So, in other words, get the CA one. They're on to us and it ain't worth a test-fail and replace. But the two CATs are the same save for the Ca number on the can.
California 339894
Yes, I hate Kalifornia and the rabid crooks who lead it.

Here is the way to look at it:
1. You are failing CO, which means that you are running rich. Either too much fuel or not enough air.
2. You are failing at 1500 RPM but not at 2500 RPM. Air insufficiency problems get worse at higher RPM. Too much fuel problems generally get better at higher RPM.
3. There is no adjustment for too much fuel at 1500. The adjustment is only for idle fuel.
4. It looks more like a too much fuel problem that could be caused by an air bleed being clogged in the carb. This type of problem often responds to the Oklahoma rebuild. If not try rebuilding the carb.
I grew up in S. Sac in the Lawrence Park area between Stockton Blvd and Martin Luther King Blvd. You can get some good tacos, pho and soul food there.

South sac has great grub, that is for sure. Pho everywhere. Your analysis is really clear and helpful. Not really sure what my next step is. I am assuming by what you have said that tune-up won't help, but a carb rebuild may be the answer? What is an OK rebuild, forgive my ignorance. My second retest expires in three weeks but I can't schedule that work before then. May as well try the tune up and hope for the best, then pass it along to valley hybrids if all else fails.
You can search for the Okie rebuild. Basically, you just hose down the insides of the carb with spray type cleaner, let it sit a few minutes, then start it, rev it up to 2,500 RPM and then cover the air opening of the carb with your hand to choke it. Repeat several times. Hand choking it causes a vacuum all over in the carb and pulls dirt out of what is plugged.
Cool. Will do
Looks like this may be the issue. I tested the vacuum advance etc and went to take my retest and failed NO this time (passed last time) but passed the CO (which I failed last time) christ. Now to get a cat installed.

I went thru this with my 85 FJ60 in Phoenix and ended up doing the following:
First time I failed (year 1)
1 - did all the stuff in the emissions FSM - still failed
2 - bought a used carb on MUD and sent it to Brandon at Marlin Cruisers to rebuild it - passed
Second time I failed (year 2)
1 - mixed some alcohol in w my gas and ran it on the highway to heat up the cat - still failed
2 - replaced the smog pump - failed
3 - new cat - passed
Third time I failed (year 3)
1 - replaced the smog pump - passed (O'reilly unit, had warranty, easy swap)
Fourth time I failed (year 4)
1 - registered my truck in Montana with a permanent plate
Permanent fix - the 1HZ sitting in my garage

That sounds sensible. May try the same thing. What a pain in the assI went thru this with my 85 FJ60 in Phoenix and ended up doing the following:

Before I make the plunge, what's the difference between the 339041 and 339894? Just the phlanges?
The difference is 3 digits.
Zing. I guess the question is, would either suffice or is there a thermo sensor port issue with the 9041?
The two are identical. Exact same fitment. The CARB one supposedly goes thru OBD II tests.
Right. I suppose an OBD II doesn't apply to my 86 60 which makes it an easier decision
Right. Wonderful Kalif just retroactively applies a standard so they can charge a tax (on manufacturer that the consumer ultimately pays).
Its a pretty bad system when your truck runs perfect and the only reason you can't drive it is because of rules that don't apply anywhere except where you live. This system rots. Oh well, got a decent install quote for the 9041 . Less than a new 9894.
Just wanted to come and give a celebratory head nod to young Gurr.
Well done, señor
Well done, señor
Back at the California smog shack yet again. Theories? Two year old cat installed. Carb rebuild time? any help appreciated.
Once again, you are really close to passing. You might consider a full carb rebuild if it hasn’t been done in a long time. Having a functioning air injection system is important too.
It is this kind of annoying smog testing experience that made me sell my 76 FJ40. I just got tired of dealing with it every two years, which is what the smog Nazis want.
