There should be a screen in the cap that you could call a filter. There is suppose to be a clamp on the choke housing to hold the hose against it to heat the choke housing.

 

Bear24/70,

I have the clamp for the hose, and it's back on. I don't know about the screen. Do you have a pic?

All you have are catalogs from aftermarket parts sellers, which are next to worthless for ID'ing anything.

The 1964/72 FORD TRUCK PARTS CATALOG is available on a CD from hipoparts.com, also sold on fleabay for a Buy it Now price of $22.00.

While there are no vacuum diagrams in the parts catalog, every other parts is illustrated, as the catalog has 1,961 pages of illustrations. There are 4,849 pages of text.

The same style of 2V carb with that port on the underside of the airhorn was used 1970/74 on all cars & trucks, regardless of the engine size.

ILLUSTRATION Section 94, page 13 from this parts catalog shows all the air cleaner parts and the hot air tube and shroud that mounts on the right exhaust manifold.

The shroud as previously mentioned was a dealer item only, not sold by parts stores: C8AZ9A603A.

Also previously mentioned was that shroud & tube fits 1968/72 F100/350 360/390's AND 1968/71 Galaxie/LTD & Mercury Marquis passenger cars with 390 & 428 engines.

The shroud has NO vacuum line connection on it.

For a used shroud, you might give Mike a call at Big M Automotive in Williams CA. Mike has dozens upon dozens of 1960's & 1970's Ford passenger cars in his yard.

btw: There is a white plastic fast idle cam mounted in the carb linkage adjacent to the choke that is notorious for snapping in two.

What is the condition of yours? The same fast idle cam was used on all 2V's 1964/74: C4AZ9F577B (Motorcraft CM492)

 

NumberDummy,

Thanks for your response. I will order that cd from hipoparts asap! I do understand that the shroud has no vacuum hose attached to it. I know you said the rubber hose coming from the air horn connects to a charcoal canister - but I have no canister. I dont know what to do with this hose.

I always look forward to reading your posts - I learn something new every time!

I will give Mike a call regarding the shroud. Thanks for the part numbers and all your help.

I need a better way to access that cd - they want 45.00 dollars for shipping!

You are correct, there is no charcoal cannister on F250/350's till 1973.

I'll call that Ford dealer in CA first thing in the AM (PST) tomorrow and see if they still have that NOS shroud. Will let you know ASAP if they still have it.

It's listed on the Ford dealer parts locator system, but this dealer has not amended their inventory since 2005, so it's prolly long gone.

The shroud fits:

ALL 1968/72 F100/350's w/360/390's.

1968 Galaxie/LTD & Mercury Marquis 2V & 4V with 390 & 428 engines.

1969/71 Galaxie/LTD & Mercury Marquis with 2V 390 engines.

1969/70 Galaxie/LTD & Mercury Marquis Police Cars with 428 4V's.

You also might ask Mike where that *&)&*& vacuum line from the nipple on the carbs airhorn feeds to.

 

NumberDummy,

I ended up ordering that cd from ebay. What a price difference! The seller only carged me $5.00 for shipping - very reasonable. Thank you for the tip.

I appreciate all you've done for me. You are the best!

I've got to find a way to compile all the information I've gathered here...

Does anyone know if it's possible to open a folder within this site?

Take the nut off the fitting or look in the opening with a mirror, there should be a screen in the opening.

 

Bear45/70,

I have plugged the hose from the air horn, and also the fitting on the choke spring assembly. So now at least the choke isn't sucking cold air! The engine still hangs up on the fast idle cam, even after the engine is up to operating temp. I'm going to have another look today.

The fast idle lever is controlled by the choke. Have you considered swapping over to an electric choke? It will solve your problems. All you have to do is swap out the black round cover and wire the choke into a switched 12 volts.

 

Good idea - just keep in mind whether it needs full switch +12V or the stator wire from the alternator

Bear, I think he still needs the choke tube going to the exhaust manifold to properly heat the choke up, right?

 

Thanks guys,

Is it really that easy to swith over to electric choke? I'll check with Napa to see how much it costs. One question though, if the choke is electrically operated - isn't it "on" as long as the engine is running? I only want the choke on till the engine warms up. I guess I could hook up a switch to turn it off when I don't need it. Let me know what you think.

As to the choke tube, Krewat, I've plugged that so I don't think I need the tube at this time. I have ordered the parts cd from hipo parts, so I hope the parts diagram will show the tube I need, and where it goes...

BTW, I've found the exhaust manifold heat shroud on ebay!:

eBay Motors: 1967-1972 Ford Truck FE Exhaust Manifold s tube 65 66 (item 270279958774 end time Dec-24-08 12:22:39 PST)

I Look forward to the day when my choke system works as intended.

Thanks for all your help,

zenmaster

 

Not with the electric cover. The way it is now, the choke will take at least 10 times as long to be completely pulled off, if it ever is. You are right about there being two different electric choke covers. The stock item and replacements for it use the stator wire off the alternator (about 7 volts), engine not running, whether key on or not, no choke heater. Engine running choke is heated. I prefer the latter one. The aftermarket ones are all 12 volts.

 

I meant, as it stands right now, for it to work right, he needs the "stove pipe" - the heated air, going from the air horn to the exhaust manifold and back up to the choke.

 

I understood that, but didn't address that in my response and you are right.
