Topic: 22r carb on a 20r intake

[lal357]

alright the stock 20r carb has given my problems since i got the truck i have a almost new 22r carb and want to put it on i got the adapter to mount it but what to do about the wires on it i know the elect.choke needs a ign.switched hot (no problem) but there are 2 more wires that i need to do something with . all this is a temp thing i have a weber but want to wait till i get a offy intake to mount it (its aways down on my mod list )  carbs have always been my downfall  i look in my haynes but that book is pretty much usless

[brainlessfool]

stop wasting time, put the Weber on now!

yeah save the trouble and put the weber on it, what are ya gunna do about the water jackets inbetween the carb and the intake on the 20r and the 22r carb will not over lap in the right areas to seel it and it will suck water into the intake i found that out the hard way my carb took a sh*t and i had a 22r carb laying around and tryed puting it on and lets just say it ran even worse

buy an adaptor from toyotaperformance.com or lc engineering to put the 22R carb on the 20R.  they're good carbs, and run better at angles when stock than a stock weber will.  they also have more CFM than a 32/36 if that matters

as for the stock 20R water choke, just run a hose from the 2 holes in the intake.  mine's setup this way and works fine...though if i ever rebuild the motor i'm getting a water choked weber, manual chokes suck!

ive already got the adapter to put the 22r the 20r intake got it from lc engineering some time ago this is just a quick fix so i can take my time with the rest th e problem is trying to find out what to do with the wires that are on the 22r carb i know thieres 1 for electric choke another for what ever is on the 20r now but the 3rd wire thats the one i'm not sure what it runs to and my pos haynes doesnt show me they all go to a connector .
carbs are any will always be my downfall  as for the weber i want to wait before i do anything with that as a engine build is in the future and i'm not sure what way i'm going yet (20r/22r or just a22r ) and dont want to buy a aftermarket intake twice

im gunna go out and look at my 22r carb and try to figure out wat your talking about i only remember 1 wire

[kyle_22r]

you only really _need_ the electric choke, hell, you probably don't even need that if you live in a warm climate.  the fuel cut solenoid is nice as well, but it's computer controlled so you'd need to grab the computer from a 22R truck(on the kick panel)

one wire is the electric choke.
-----ignition hot.

one is for the idle fuel circut cut off silinoid.
-----ignition hot.

one is for the carb float bowl vent control dealy bob. 
------i'm not sure when this one turns on.  but it's just the float bowl vent.  i'd try ingnition hot wire with this one as well.

stock 22r carbs are good carbs and they do have more CFM than both the 20r and the 33B weber.  i think they have their good pionts over webers, though i do prefer webers over stock.


hope it helps.

I'm not so hot on reading wiring diagrams, is ignition hot the black/yellow wire running everywhere? It runs off of several components and links together but I don't know how to identify if this is the wire I'm looking for. I'll stare at the diagrams for a few more hours and see if I can wipe stupid off of my face.

Thanks,

Bryce

Never mind, I think I just answered my own question with the FSM diagram. Sorry for the unwarrented post.

ok got barney(22r) in and hooked up except for some vaccuum lines that will probably be pluged off ran fine .when we poured gas down the carb it fired right up  now to address the wires from the carb i have a red wire that goes to the electric choke , a black and a white wire that  goes to something on the passenger side rear of the carb and a single black wire that is running to the passenger side front of the carb.
i have a ignition hot already ran i just need to know what ones need to hook up to it and what ones need to goto ground .after almost 2 yrs it sure was nice to have fire up damn near instantly and run as long as we pour gas into it (the carb)
any help ? anyone done this before
