So many updates...
The Shop / Carb Rebuild
Took the car up to the shop a few weeks back to have it checked out tip-to-tail. Some friends recommended a shop local to me (about 30m away) that really knows land cruisers. Ended up chatting w/ the owner for about an hour, he's been driving 40s and 60s since he was in his teens. Anyways, while I had it up there, I decided to let them have a go at the carb. Sure enough, I had a vacuum leak and the idle circuit was clogged. Some other notes from the carb rebuild:
- Apparently the jets were too small for high-altitude, they put in the correct ones
- The spring on the accelerator pump ball-bearing/BB was just not there
- They said it was one of the dirtiest carbs they've ever seen. Upon further inspection, I have some crud/rust floating around in the gas tank and the inline glass filter I had wasn't fine enough to stop it all from getting to the carb
Added more to the "to fix list" after the time in the shop, they recommend radiator/hoses, new suspension bushings and leaf springs (you can see the old bushings pushing their way out, they are beyond gone), and of course a replacement gas tank. A few other odds and ends but overall the truck is in good shape.
I also had them look at the brakes, as the parking brake doesn't, and they seem a bit anemic to me overall. I have the rear drums with two pistons per side, and the owner says those are a PITA. He recommends swapping them out for drums from the later 40's or a 60 with a single piston, as those are easier to adjust / keep their adjustment. That or swap to discs.
Emissions Round Three
Truck is running super smooth since the carb rebuild, although I have been religious about cleaning out that glass filter. I don't need the choke to keep her idling and idle RPM is around 690ish. Was feeling confident about emissions, but failed again (high HC/CO)

. From what I'm seeing, I should try leaning it out and retarding the timing... That will be this afternoon to play around with. A few notes for those in Colorado (at least up in Boulder county where I am), there is no visual inspection of equipment at this point. Have passed "visual" all three times. The shop owner told me they really just focus on what's coming out of the tailpipe. So I'm going to keep at it and not worry about a cat/re-smogging it.
Tinkering / Misc Fixes
Boy, can I say how awesome the wealth of knowledge is here? I feel like half my searches are on this forum now. Been busy since I got the truck back from the shop, ticked a lot off my list:
- Replaced headlight switch with the proper part # (previous one was from an older '40 that had headlights/corner lights on same circuit, and the knob was broken as well). Lights / corner lights all work, no blown fuses.
- Adjusted headlight aim (was a bit catywompus)
- Fixed the oil pressure gauge: Found a loose wire in the engine bay, traced it out, and sure enough that was it.
- Fixed the odometer. I was intimidated by this one, but ih8mud to the rescue. Spent a good amount of time reading through this thread and it worked a charm. The number dials were so stuck on there it was a bear to get em loose, but persistence paid off. Works great now that they are cleaned / re-greased.
- Cleaned all electrical contacts in the gauge cluster (the round plug) and added dielectric grease. No longer getting flickering / inconsistent gauge issues. All the foam inside the cluster had also disintegrated with age, so I replaced that with thick felt attached with 3M super 90. We'll see how it holds up.
- Swapped the bulbs in the cluster w/ the high-output ones from CCOT. I can see in the neighborhood now, although I think stock bulbs might be fine as long as you deleted the light baffles inside the cluster. Time will tell on those.
- Got rid of the mystery circuit board/wiring. The only thing it was actually connected to was a small pressure switch screwed into the dashboard framing and the power cable that would normally be used for the dome light (which is missing). I think it was likely a radio or something, but who knows.

- Added a few bits and bobs from CityRacer (door hole plugs, spare tire latch bumper)
Next up I'm going to address the dome light, air intake (going to try to fabricobble a replacement for the air intake horn, which is apparently made of unobtanium), and see about replacing the Ingition Coil with something stock (it is some aftermarket thing, and Id rather this truck be as stock as possible). Im presently trying to figure out internal resistor vs no, whether I need an igniter (some people seem to bypass them?), etc etc.
