New 2F carbs

[Trollhole]

Doesn't come with the base gasket. You can make or or most likely get it from a parts place. That is something I have yet to do.

Have to say I have a fellow UC member that just installed this carb and drove it up to Tenn today through the mountains. Said it did great and even with all the steep climbs he managed 15 mpg in a loaded down FJ60. Said power was great. We should be getting a detailed review from him early next week on the results.

Will the cork stuff be ok for gasket material or do I need something better?
Got the old carb off, everything cleaned up and ready to install the one--wife thinks I'm nuts because I'm all excited

 

[Trollhole]

Probably wouldn't use cork. Most auto parts houses have sheets of gasket material.

 

[tclark]

Thanks; guess I've just never seen it before--reckon I'll pick some up

I'm interested

So I have a 9/72 F motor with the original carb. The accel linkage is cable from the pedal to the base of the carb where it attaches to a bell crank that moves a rod on the carb to open the throttle. The pictures make more sense than I do. So a couple of questions:
1. Do you have a set up that will work with this?

2. Also, is the air intake at the top of the carb the same diameter (F vs. 2F)? Mine doesn't have the bolt down the center to hold the stock air cleaner in place, just a clamp on the outside.

3. Lastly, my fuel inlet is on the valve cover side of the carb, would I have move the line around to the front?

I'm really hoping this works, new carb and dizzy would be nice.
Thanks, Dave.

I have never seen linkage like that. Very interesting.

1. I would think that linkage would work with my carb.

2. Another grat question. Can you give me the outside diameter of the carb air inlet? If it is not the same as the OEM inlet (which I'm pretty sure it isn't) I'd fab something up so it will be. Also would be nice to have the height of the carb. From the bottom of cast iron base to the top.

3. You have two option you could bend the line to make it work or you could drill and tap the valve cover side of the carb, move the fitting over and plug the other side.

I'll have to get those measurements for you tomorrow. The carb is the original stock Aisan 2 barrel and is stamped "2 I 22", which I take to mean September 22, 1972. '72 and '73 seem to have some pretty different set-ups, which has tripped me up several times when trying to source parts.

That linkage is attached by the 2 bolts on the drivers side of the carb base.
The air cleaner is pretty stock for an F, wingnut through the filter, clamp on the carb.
Like I said, I'll take measurements and get better pictures if you'd like. I'm pretty stoked to make this work.
Here's a link to what I have. <-- (link from SOR)

My 73 had the same bellcrank settup. They were that way for a couple of years Marshall. It is a possible way to hook up the cable actuated carbs. I personally put a 77 carb on my 1F and made up my own way of mounting the cable. But I have sourced a bellcrank, and I think it would work on a 2F carb, but there is some interference with the secondary return spring on the 2F carbs and that bellcrank assembly. I have not tried hooking it up, just held it up, but a little grinding may make it work.

As for aircleaner attachment, that is a good question. 2F carbs have a small lip on the top of the carb and rely on a center sud to hold the aircleaner down and sealed. 1F carbs had a tall lip on the top of the carb, no center bolt and used a large hose clamb basically to hold a rubber connecting boot to the carb and aircleaner. I think a 1F air cleaner may work agianst a 2F carb, if a hole was drilled for the center stud and some creative gasket work.

However, the distance from the head, and rise of the intake manifold are different between F and 2F engines, so the height of the top of the carb changes. I used a 2F aircleaner on mine, as I already had a 2F valvecover on it. But I had to lower and offset the aircleaner towards the passenger side of the engine to make it hit the top of the 2F carb, on the 1F intake manifold. That required making new brackets for the mount to the top of the valve cover for the aircleaner.

I can make anything if I can just figure out what to make.

I do have a aug 1970 carb sitting in front of me. Ironically the top is the same diameter as the 2f carbs. Though the lip is smaller. The stock 2f carbs are about 10mm higher than the early carbs but I'm in luck as my carb is 10mm shorter also. So the height is the same on my carb and the 70-74 carbs. That being said my fuel line mounts to the front side of the carb. So you would have to reroute it or i would think it would be easier to just tap the valve cover side of the carb for the line and plug the other side.

Then all would be left to do is figure out the throttle linkage. And for those with the regular throttle cable with simple mount I think I have a solution. A very simple one.

Basically use use your old bracket with a small cut in in the base of it so the choke braket fits over the top of it. Then all you need is to cut off the led throttle stop on your cable and install one that will mount on throttle arm. There is a hole already there and go on the backside of the plate.

All I need to do is source out the cable stop.
Like this one.

Measurements

Sorry these are non-metric. All my metric stuff is back in my classroom. Perhaps somebody can do the fancy math and convert.

First picture: Air intake is 2 and 15/16"

Second picture: Height from bottom of cast iron base to top is 6 and 1/8" (NOT including insulator w/PCV hose connect)

Third picture is the snap on linkage (disconnected) which looks compatible with what you have.

If I can figure out how to attach the stock air cleaner and re-route the fuel line, I think it'll work.
But then I am an eternal optimist.
What do you all think?

 

[Trollhole]

can you take another pic of the cable linkage especially where the spring mechanisim is. I think that part may get in the way of the secondary.

Got the Carburator almost two weeks ago, but then went on Vacation. Great Carb just like the original. Can't wait to install it and the try to figure the desmog process.

I think the biggest thing that may be near the secondary is just the eye to hook the spring to, the bracket doesn't really take up too much room. I'm not the best with this camera, hope this helps a little.

 

[Trollhole]

Well that won't work. The secondary vacuum mechanisim sits right in that spot.

Paypal sent for carb and dizzy. I am so glad I came across this thread as I was actually contemplating rebuilding my carb myself. TIA.

Went out today as well I processed your refund and even tried to spread a little cruiser karma.

 

[tclark]

Got my carb in this evening---looks great! It looks so simple and elegant without all the smog stuff! I'd take some pics but I have no clue where the camera is. Everything bolted right up though, no problems at all.
Thanks for getting it out so quick (love the packing material btw)!
Oh, what's the little chain for on the throttle linkage coming from the pedal? Looks like a ceiling fan speed adjustment chain. I don't think it was hooked up before.

 

[mixerman]

I picked up my carb at the border today. put it on as soon as i got home my 40 has not run so good since I bought it. starts with out the choke, idles smooth,no hesitation and way better power.Definately the best $ 225 I have spent on my 40. thanks marshall.

Never heard or that.

Posted my writeup on the carb over in the 60 series section.

The 2F carb on my Cruiser runs better than expectd. Thanks Marshall!
