Yeah, I searched....(76 Pig 2F Tech Query Inside)

IIRC, Trollhole carb does have AC idle up provision.

I'll check mine today that I have on the shelf.

IIRC, Trollhole carb does have AC idle up provision. I'll check mine today that I have on the shelf.

Can't confirm, nor deny, but did arrive today. Have a diagram of the non-US lines...somewhere.


















Kinda curious/concerned about overall height, but have no clue if the 3F manifolds are at the same elevation as the 76 2F intake, but the plastic (??) spacer appears to be irrelevant.










What's throwing me off, too, is Trollhole's PVC cleaner spacer, since the balance of the carb appears to be significantly taller than the OE...






Insulator...











Hope it all fits.

Further down the rabbit hole I go.

IIRC from my swap the 3F head is shorter than the 2F, I'd imagine that adapter is for the earlier canister type filter (most places never went to the across the motor type). Can't wait to see some progress, sounds like fun!

the tab on the link to the left is where the idle up plunger hits, if it's similar to the 2F...

Though the filter is the lesser of concerns, is the remote, for lack of a better term, filter doable?

Way I understand it, there's little difference beyond the base, to any corresponding OE non-US 2F.

check #60 on this page>http://www.sor.com/cat053b.sor...#60 is the vsv which switches the vacuum from the nipple on the manifold to the rear of the carb, next to the brake booster nipple, to the diaphram mounted to the carb base, which pulls a lever and cams a screw to push that tab I mentioned in the last post...which opens the throttle plate by turning the shaft it's mounted to...the manifold nipple and idle up solenoid aren't numbered in that pic on the link, but the lines go directly to them, if you follow them from the VSV, #60...

the aisan 3f carb ,when tuned right is amazingly smooth and trouble free and will operate at some extreme angles.

Most of those vacuum hoses are for the aircon fast idle up,its quite simple once you understand it. I think some go to the charcoal canister and distributor?

the internals,linkages and castings for the secondary are all the same between the 2f and 3f carbs.

The only major difference is the 3f accelerator pump is activated by way of a cable and the cast iron base has a different bolt pattern. (the only reason i know this is because i have roscos old carb) :d

that being said, are you sure you are diagnosing the problem correctly? The secondary is activated by internal vacuum at very high rpms and heavy load (around 2,600 on the 2f and not just free revving) do a few searches, the info pertaining to the 2f secondary should be able to help you with the 3f.

it will look like a non north american cruiser. This is my 3f in a 73 series before the diesel swap. It sure makes them simple to fix:d the 4 hoses on the right are related to the aircon fast idle

hey rosco, what is that thing on the intake mani close to the engine? Is that a vac line or a electric switch?

that's a vacuum port for a/c high idle.

snorkle it

Funny, cause Rosco replied to the affect "snorkel won't make it go faster" in one of the threads perused.

No need for a snorkel at the mall.

you need vac source, switching valve, and diaphram with mounting bracket for carb base and link tab to pull throttle arm. that THC carb should support that...ToyoDIY.com 1987 TOYOTA LAND CRUISER (FJ70LV-KN) my cars ▼

For easier picture reading.

Is it possible that Toyota part number 21100-61300 3F Carburetor was not Aisan manufactured or badged?

Just a question of curiosity (I know what you're thinking, Sunshine) I swear.

 

[Delancy]

Had been looking forward to mocking this up for some time, but tore into the manifold box and the carb studs didn't seem to make it, so, improvised a bit.












From the top of intake manifold with the Trollhole 3F carb and spacer.



Same location with Aisan.



Have to say, having handled a few of the earlier F manifolds, the three piece design does seem a huge improvement.

The ports may be due a but of clean up, guess that decision can be made by the builder, but it all looks good together.

Look better in here...

Holy hot unobtanium.....

Well, the oil cooler is still available in the US.

 

[tucker74]

Wow,

Got a box from UAE once, never from there ... they throw in some saffron?

LOL

[Delancy]

I've actually communicated quite a bit with the seller and he's an LC enthusiast that bought 8 fully laden shipping containers full of Land Cruiser parts from Aichi, then had (4) shipped to Iran and (4) to Dubai.

I'm, all but, certain I've bought from the same guy, many months ago, and received package from UAE, but haven't spent the time to confirm.

Anyhow, I did have to sign for, it was searched, they destroyed the oil pump box and discarded most, destroyed the cooler box, but re-taped, oddly enough.

I've seen a very small listing of the inventory he has, the majority of that being 40 specific, but he does have NOS 55 window regulators, (69801-90351, 69802-90351, 69803-90352, 69804-90352) so I'm holding out hope that weather stripping is in there somewhere, along with an 85-87 2F(3F) NOS head and NOS power steering gearbox.

Who knows?

 

[Delancy]

Had perused the "Ultimate 55" thread some time ago, but hadn't considered relevant until revisiting.

Does offer options that were previously unconsidered, so posting pics for reference.
