update to 'dumb girl in WA state needs help'

[karladaune]

ok, so i made it down to the beast, but then my camera started acting up (the past week has been a total comedy of errors.) I got a few pics, but I dont know if its enough to be able to identify the carb, as I wasnt able to get a full carb shot. Through the caked on mud, I was able to identify that it is a Holley carb of some sort - looks like the diagram of the 4160 in my chiltons manual, but i cant seem to find the tag or the stamp on it.

Anyway, I dont seem to see where the electric choke housing is and these diagrams arent too helpful. I have posted a few pics to fullsizejeeps.com with the intent of inserting in this message, but my file resizing isnt working. If you follow the links below, you will be able to see the few pics I was able to take before the camera died.

I'll be going down with a different camera tomorrow, but meanwhile, any input on what I'm looking at would be appreciated...

Sure looks like a holley, on an edelbrock intake. Looks like it has backfired quite a few times, too. I'm not much on the holley carbs, but that may be a manual choke setup intended to have a cable. I can see the goldish lever arm on the front part for the choke, as well as the goldish bracket behind it for holding the cable.

[youngjeeper]

not sure bout your carb, but thats a nice chero!

[La Wagoneer]

The reason you don't see the electric chock housing is that there isn't one. The carb is a holley 4160 of some sort. Clean the front of the air horn and the carbs' numbers will be stamped there. It looks like someone changed the carb out at some time with one with a manual choke. To get the choke to work you'll need a cable run to the inside of your rig or Holley sells a update kit to convert to an electric choke. Go to Holley's web site they have lots of great info and a parts identifier.

[Stuka]

Thats not an edelbrock performer. Its got be some other intake. Maybe the series edelbrock offered before the performer. Or maybe a holley dominator intake.

[karladaune]

yeah, i havent driven it much, but it has backfired alot each time i've started it :(

It will be a nice chero if I can figure out how to work on it! P.O. hacked the fenders tho to make room for the tires, not sure what i'm gonna do about that. He also put cherry bombs on it :( my neighbors hate it.

Backfiring through the carb can be timing. Check the spark plug wires for the correct routing and check the timing. Backfireing through the Holley can also blow the powervalve which is not expensive or difficult to replace.

[tgreese]

It's a 4V Holley with vacuum secondaries.
http://www.nmr.mgh.harvard.edu/~reese/CarbPic.png

It has a manual choke - the choke should stay open by itself if you move the lever. The 4 barrel (4V) carb has primary and secondary barrels. The primary is used for idling and put-putt-ing around town; the secondaries open when there's more demand for fuel. The engine is like a big air pump, and creates a vacuum to pull the needed air/fuel mixture into the cylinders. Here the secondaries use a vacuum servo to open - when the demand for fuel is high, the manifold vacuum is low and the secondaries open.

Ok, so which part do you have to block open to get the engine to run? The choke works only on the primaries; the plate for the choke is in plane parallel to the top (or air horn) of the carburetor. You can move the choke lever to watch the action of the choke plate - open to run, closed to cold start.

Tell us more ...

Is that an old Edelbrock SP2P intake? If so, hang onto it - don't let anyone talk you into changing to a Performer.

[karladaune]

ummm...is there anyway to identify the intake? I have NO CLUE what it is, nor did the most recent P.O. He had bought it a year before he sold it to me from a guy that worked at a local parts store here...no telling what he put in it.

Mark in WA - i take it an edelbrock SP2P would be a good thing to have? What are the pros and cons between an SP2P and a Performer?

[DieselSJ]

SP2P's aren't made anymore and are very hard to find. They make better all around power on a AMC engine than the Performer.

The manifold should have the name of the company cast into it. It looks like it is right in front of the carb, but the pics aren't clear enough to read the name.

[bvibert]

It looks like the Edelbrock script on the runner behind the carb. I would imagine it should have some sort of casting indicating what model intake it is also... The Torkers do...

[jeepguzzi]

Could it be an Offenhauser intake? I saw one at a speed shop once. It was used.

[karladaune]

ok, its definitely an edelbrock intake...dunno what kind tho. Also found the stamp on the carb, but hell if i can read it... :-(

[Joe Guilbeau]

Fer Christ's sake, clean that engine bay!!!!

[karladaune]

you should have seen what it USED to look like under there...i swear it looked like someone popped the hood, and backed a dumptruck full of mud up to it. It was HORRIBLE.

i've got virtually no time between my kid, my mom, my dogs, and work, but its DEFINITELY gonna get cleaned before it comes back in my driveway! (hopefully that'll be next sunday)

gawd!!!! sorry for the double post...i'm not sure whats up, but this isnt the first time i've done it tonight. i must be heavy handed on the ol enter key...

Thats alright! If you want to though you can delete the duplicate post by clicking on the edit button http://www.ifsja.org/ubb/edit_ubb6.gif at the top of one of the duplicate posts. Then click on the "Delete Post?" check box and hit edit post at the bottom and it should be gone :D

[karladaune]

Thanks Brian!

[710 Burner]

The model number for that holley should be on the metering block right above that distributor vacuum port that is not being used. The other place Holley put them is on the choke stand, next to the air horn.

[Wesdog]

Looks like an Edelbrock R4B intake. If so you got a very desireable manifold that is worth some bucks to the AMX crowd.

[karladaune]

wes,

that looks exactly like what i have...hmmmm....one mystery solved??

[Wesdog]

We'll that'll get the boy's worked up! Those into racing AMC's really covet the R4Bs and they are pretty scarce.

[karladaune]

maybe this truck will turn out to be a diamond in the rough after all (or at least a cubic zirconia!) I pd $500 for it and have kinda been kicking myself...

[Wesdog]

Karla, looking at the photos I think you got a good Cherokee. Don't know what the interior looks like but I suspect the engine just needs a little work to get it back to where it should be. If the engine area got loaded up with mud then there are probably some ignition system parts that may need attention once the carb is fixed. Probably nothing that expensive. Has the oil been checked/changed recently? Don't kick yourself. I'm sure you could sell it for more than you paid for it. Do you know whether it has a 401 or 360 V8?

[karladaune]

interior isnt all that great...no door panels, strange rubber matting on the floor, nasty floorboards. On a positive note, headliner and seats are all in good shape.

P.O. thought it had a 360, mechanic friend who worked on it said he thought it had a 401 - yet another mystery to be solved.

The only work that i've done to it since i've had it is a bunch of brake stuff - back brakes were virtually nonexistent. Had to replace the proportioning valve, drums, shoes, lines, and the master cylinder. It could definitely use an oil change and a tune up, among other things.

I have the number of a local guy from the board who is willing to come down and take a look at it for me so I at least have an idea of what i'm getting myself into. I just keep reminding myself that it was bought for the sole purpose of transporting my 3 big mutts to the river and hiking without having to worry about them thrashing the inside of my car...I didnt PLAN on getting addicted!

[Wesdog]

The block will have large raised numbers on the sides by the motor mounts, either 401 or 360 (I think the 360s are marked, I know the 401s are with few exceptions). With the R4B intake I'd bet it's a 401 but that's just a guess. What year is it?

[ September 16, 2003, 11:33 PM: Message edited by: Wesdog ]

[karladaune]

its a 76...however, my chiltons guide says that the 401 didnt come with a manual transmission.

Pat (P.O.) is a total dip, and I am much more inclined to believe my mechanic...but if they didnt make em with the manuals, I dont know...

[Wesdog]

I believe you are correct, the 401 was only offered with the TH400 auto. My 76 has the 401/TH400/Qtrac combo and my 77 has the 360/T18/D20 combo. Still worth a look at the block though, engines can be swapped and a 401 will mate to the T18 so you never know what you might find.
