Jim, if the EGR went through the spacer, they erode badly to the point of warping and leaking. Ford started supplying cast iron ones as service parts, we kept a 2 and 4 barrel on the shelf at Preston.

Make sure there are no small pieces of gasket adhering to any of the surfaces and do not use any kind of sealer under the carburetor.

On points, I have a 1970s vintage Poulon Super 25D chainsaw, I tried a breakerless conversion on it, no go, so I have a spare set of points in my toolbox for it. It is old enough to not have a priming bulb and you just have to keep pulling it with the choke closed until it fires, once you get that it will start and run fine.

Well the sandpaper should take care of any gasket residue.
And it will show erosion.

I can't say I've seen an aluminium EGR spacer on a Ford.
Maybe aftermarket, but the factory iron ones don't seem too bad.

I think better to examine than to just throw parts at it.

Ahhh! Yes, those would take points.

As for the old man shaking fist at clouds emoji, I didn't find anything that seems to fit that description on FTE. And I didn't find something in my searches. So, can you point me to one?

Re: Carburetor/Throttle Help

What material is the spacer supposed to be made of? Mine is not metal and the EGR does not run through it, unless I am really missing something.

I think you need to post a pic of that spacer.

Assuming that your truck is a 2bbl, the original spacer should have been cast iron or aluminum. And there would have been an EGR valve hanging off the back of it. So if yours isn't metal then I don't think it is original.

As for the exhaust gas, it comes in via the intake manifold, up into the spacer, and then into the air/fuel mix. Perhaps someone put a spacer on that blocks the EGR port in the intake manifold?

Post a pic of the intake manifold surface that mates the spacer as well.

I've never seen a phenolic spacer from the factory.
If you have an aftermarket intake without EGR, then all this talk is redundant.

Jim, I have seen factory phenolic spacers, not on the trucks, but on cars, I believe it was on my 1970 and 1971 429 engines, roughly 3/8" thick and the PCV system came in the back and went around through channels molded into the spacer so it fed the fumes into both primary throttle bores.

You've seen a LOT of carburetors Bill.

I'm talking about the truck this thread is about.

We don't know the history of his truck, since it originally had a VV on it, it may be a 351M.

Re: Carburetor/Throttle Help

But he says it's phenolic and the EGR doesn't run through it.

M or W, it doesn't sound like a stock '82 intake.

If he posts a pic we can all see what's up.

EGR appears to in the manifold itself.
There are no passages in the spacer to erode or leak.

Shaun,

The carburetor base appears flat and should seal
Rubbing it on a flat surface with a sheet of 180-220 grit carbide (black) wet-or-dry paper will highlight any warpage.

Just take your time, and don't rock the carb at all, if you can help it.

Jim, Shaun, the vacuum passages in the throttle body may be coming outside the strange intake mounting area. This may result in the carburetor not sealing properly. The other item, the mounting gasket does not appear to have the hard reinforcements around the mounting holes. My suggestion would be to find an aluminum adapter like was used to mount a Holley pattern carburetor on a GM or Chrysler manifold, or vice versa. Use it and two thinner gaskets, if the adapter has one side solid and one with it fairly open, put the solid side down.

Bill,
Isn't the phenolic spacer used to isolate the carburetor from the heat of the intake manifold?

It's got to be hot if the EGR gases are flowing through it, no?

Re: Carburetor/Throttle Help

If the phenolic spacer isn't warped, then yes, but it will still need a pair of gaskets, one under and one over. They need to be reasonably hard so they won't compress too much. The spacer may have some uneven areas as the VV base is different that the Holley base.

Hello; My name is Randy and I have the exact intake but a motocraft 2150 carb. Having vacuum leak and idle problems too. Did you get your's resolved and if so what was the solution?

Re: Carburetor/Throttle Help

Hi Randy,

I am 99% sure that my issue was an amateur carburetor rebuild job. I took my carburetor to a professional and had it rebuilt properly- it needed it! Unfortunately, at some point in all the carburetor work I lost spark and haven’t been able to fix that issue. Make sure you have the right gaskets and take your time. Keep asking around on this site- the guys here are extremely helpful. Let me know if I can be of any help.

Re: Carburetor/Throttle Help

Sorry its taken me so long to get back to you as I've been extremely sick for too long.
As far as rebuilding carburetor I've done that twice + ordered a remanufactured one so I'm going to rule out the carburetor on mine. I think mine could be the phenolic spacer and or the carburetor base being somewhat uneven/warped. I'm still a little sick and don't want to work on it as the temperature is in the low 40s and dropping + it's misting. Anyway sorry to hear about the spark problem. I installed a cheap HEI distributor on mine and connected it to the white wire that powered the EECIII brown grommet ignition box. It seems to work well but is a bit tight if you have factory A/C.
Good luck on finding the spark problem and hit me up if I can help as I would be looking at the same set up as your's. Seems as though 82-83 had some rarities aka the intake manifold itself! + crappy carbs.
