2F Carb Vacuum Routing de-smog

[Bostonfj60]

I just finished putting the header on the 40. The truck was 80% desmoged when I got it, so I just finished it up.
The only thing left was basically part of the EGR system. All the vacuum lines, ect had been pulled, and the associated vacuum ports on the carb were capped.

I attached a diagram that has a number of things marked. My main question has to do with the two vacuum lines that run from the distributor and to the carb (the vacuum advance). I thought on my 60 the two vacuum advance lines were attached to the carb itself (possibly in port 1 and 2) and NOT to the air cleaner itself. Before I did the header, the truck had good power, but idled very rough, especially when it warmed up.

I also recall at least one vacuum line going from 4 to somewhere on the carb (on my FJ60)
and what is 5?

So, please make comments on my diagram...anything at all that does or does NOT look right to you.

Thanks !

I just desmogged my 60. I've got the outermost advance port on the distributor to one of the ports on the valve cover side of the carb. The inner dist advance port is routed up to the air cleaner. Look up Fowldarr's (I think thats how it's spelled) Desmog thread. There are some awsome pics on pages 3 and 4.

Dumbass Questions-

How hard is the desmog procedure for the non-wrencher? Does one replace the carb or use existing?

It's pretty involved. The thing that makes it difficult is the conflicting information flying around. Jim C has some good info on the desmog. To do it right, you should send your carb and dissy to him for a rebuilt/re curve.

Its funny though, my desmog (on my 40) was done kinda wacky, but at then end of the day, it still ran fine.

You have a 60 rights? I desmoged my 87 and that was a bear...there are A-LOT of vacuum lines. Lastly, in order to access all the information out there, its almost imperative you can read a schematic diagram (like the ones in the back of service manuals) This was hard for me, as I SUCK at understanding those things...

Does anyone have a series of picts of a desmogged 2f / fj40 engine? I would like to do mine as I think it is partially started ( I just bought the FJ).
Thanks.
