What have you done to your truck today?
Picked up a BWD lifetime warranty headlight switch, the one year warranty one I got to get my dash lights working after I did the LED swap went full defective and wouldnt give me dash lights or parking lights but would turn on the dome light and the headlights.
So will be installing that tomorrow at work since I dont have much to do since I got everything done today. I also need to put that carb for that '59 Ford 641 back together I have it soaking in our carb soak over night.

I finally got around to hooking up the LM-2 AFR meter today. The new engine won't go in until spring, so I wanted to get the old one as tuned up as possible for winter.
I installed the idle solenoid last week, and thought the idle sounded a bit off. Once I got the LM-2 figured out and calibrated, I went ahead and installed the sensor, warmed her up and checked the AFR.
What a shocker! It might explain a few things, but the AFR was 18 or so. WAY lean.
I tweaked it a bit and got it pretty stable from 14.8 to 15.0. I seems to idle smoother, although I didn't get a chance to road test.
In any case, the fuel mix seems to be set correctly now.
Time will tell..
(I also picked up some gauges for my engine test stand. Getting closer..)

If you can't get it any richer you may have a vacuum leak. But if it runs ok and the air cleaner is heated you should be ok until you can get the new engine in.
Rejetting won't help the idle mix as the idle fuel flow is well below what any jet will pass. But there are idle passage restrictions in many carbs that limit the amount of fuel, and that's probably what is keeping it from getting rich enough. You might find something on it by Googling it, but most of the restrictions can be reached with a drill bit to enlarge. Here's a link to how to do it on a Holley. I don't know what a YFA has, but most carbs do have a restriction.

The idle jet is actually an idle tube, standard size is .027 as I recall. I have a spare from another carburetor; I may replace it just to check
