All I can say is wow.
If I wasn't going to thrash Bessie off road I'd do some serious body work with nice paint. But she's getting the rust out and a flat black primer coat. No point in putting on a pretty coat only to have the local trail flora scrape it down to primer... I know if I worked as hard as you I'd CRY if it got scratched or dented!
A+ job, bro! And I love the sticker!

Yeah holleys are good, I just got done removing my flywheel though since the clutch actually came apart a couple weeks ago, I think the cam was the nail in the coffin for the clutch, but boy does it sound good

So did you ever get that air fuel ratio setup going, you were talking about using that one from ww2 fighters. Did that ever work out?

Nah, turned out to be a lot of A/F gauges from the A6M zero and Ki-43 Hayate series fighters that used a thermocouple in the head pipe to approximate the ratio.
Truth in advertising FAIL on the seller's part.

I went with a modern unit with a bunch of features that could be put to use for sensors and EFI should I give up on the carb thing.

Hmm it would have been cool if it worked, Im looking at certain A/F ratio setups but I think im gonna get headers first.

This is a narrow band unit and is the best bet for the dollars I've found so far:

This is what I bought instead....and not working yet

Thanks guys for the words of support!!

OK, today's drama is a continuation of this week's DRAMA....

I've been trying to get a standalone Air-Fuel Ratio meter system working on the Blair in preparation for the Holley 4160 with a manual mixture adjustment system.

I got the second Innovate Motorsports LC-1 kit after the first one was DOA out of the box.

Got this one installed and have been fighting the unbelievably L E A N readings coming from the O2 sensor.
The target is 14.7:1 (1.0 Lambda) air/fuel and so far I've been seeing up to 60:1 ratios which just seem impossible to believe. The Blair runs too darn good to be this lean so I figured the sensor or the LC-1 unit or BOTH are pathological liars.
Now, I am no so sure.....
I setup a lab grade 12VDC filtered and regulated power supply and pulled the LC-1 loose from the Jeep to isolate any ground or power induced problems.
I did a free air calibration of the O2 sensor and it showed a nice 20.8% O2 content in the atmosphere which is a standard.
I then installed the sensor into the exhaust pipe bung and fired up the LC-1.
Without the engine running, the meter and unit showed a 12:8:1 air/fuel ration in the pipe.....Hmmmmmm
Starting the fully warmed engine took the ratio to between 40 and 60:1 then settled down to an average of 22.4:1 AFR.
I started a logfile recording of the readings in LogWorks as seen below.



At :32 through :35 seconds I did several full throttle stomps which yielded a low of 11.2:1 AFR briefly.
At the :45 mark, I killed the engine.
About 10 seconds later, the readings began to drop toward something close to NORMAL for a well adjusted running V8.
[NOTE]The two rising areas in the plot after engine shutoff were caused by the wind blowing across the tailpipe. I noticed this and shot some compressed air into the pipe and got a nice LEANOUT during another engine off test.
I pulled the sensor out of the pipe and soon it was reading 20.8% O2 like it did after calibration.
Another test I did was exhale cigarette smoke onto the sensor which caused a brief drop to 9.2:1 AFR then a massive jump to 65% as the O2 from my breath hit the sensor. Back when I was a Nevada smog tester, I would calibrate the analyzer then exhale into the probe which would read as about 2.8% CO's, then show the customer how clean their newly smogged rig was in comparison.

Anyway. For some reason, I am beginning to think the problem here is with the Jeep and not the meter kit.
Below is a shot of the #3 spark plug after a good hard run down the freeway at 3500 RPM and a fast shutoff to read it. This plug is on the side with the O2 sensor and closest to the center dump of the manifold.



One would think that running so darn lean would cause pinging/detonation, melted pistons, sluggish acceleration, hesitation and other ugliness. Truth is, she runs like a scalded dog from stop to 90MPH (Where I get scared and back out of it). I estimate my 1/4 mile ET would be in the 16 second range based on many years of experience drag racing.

I checked for exhaust leaks or fresh air being sucked into the exhaust pipe and vacuum leaks. There is no A.I.R. injection system and the ports are securely plugged....with no leaks. Base timing is 8 degrees BTDC, mech advance is IN full at 2500 @ 26 degrees and a total advance with vac adv is 32 degrees at 15" of manifold vacuum under no load freeway cruising at 3500RPM/72Mph. Head temp was 175F, water crossover temp was 160F, cylinder bore temps were 200F and oil pan temp was 190F at the sump. She averages 17-19 on the highway if I drive smart and stay under 3200RPM and in town nets roughly 12MPG.
Oil consumption has been 1 QT in the last 14 months and that is due to leaks mostly.
So, as far as the engine is concerned, my experience tells me it's healthy. I don't know about the advance curve as this is an unknown Mallory HEI unit.
Some have said camshaft and ignition advance curves will affect the O2 levels in the exhaust even though combustion is decent, clean and makes good power.

Any ideas?

If I have my way, I'll have a surplus 1406 hehehehe.
They S U C K on inclines so be ready for lots of blubbering as you climb a hill with a camber to one side....then the front end bounces. Flood city my friend.



Good luck with the swap!

I'm looking into getting the offroad kit for the eddy. The Holley loves to vapor lock on trails with lots of inclines. So my only other option would either be electric fuel pump or fuel injection though I'm watching your thread closely to see how your carb modification turns out.
