This is probably gonna be a dumb question as I have very little experience with Fords.

On a 67 240, my distributor does not have centrifugal advance All I see is the base plate for the points and condenser and where the vacuum advance linkage attaches to that. I've never seen a distributor w/o centrifugal advance.

It had a vacuum advance originally, but someone removed it, but for what reason, I don't know.

C5TZ-12127-AD .. 240 I-6 Distributor / Marked: C5TF-12127-AC / Obsolete

1965/67 F100/350 & E100 with M/T; 1968 F250/350 with M/T; 1969 E300 with M/T

C0DF-12370-A .. Vacuum Advance (Motorcraft DD-12) / Obsolete

Use with distributors marked C5AF-12127-AD & C5TF-12127-AC (and etc).

Advance also used on 1960/63 Falcon/Comet with 144/170 I-6's.

Did mean to say centrifugal advance? I previously stripped the dist down to the pic as seen.

The centrifugal advance weights will be located under the breaker plate.

No.
FoMoCo called the Vacuum Advance a Diaphragm Assembly. AFAIK, FoMoCo never called it a Centrifugal Advance.

The vacuum advance (diaphragm) is present, I removed it earlier. It's the centrifugal advance I seem to missing.

I sure don't see it. Does the above pic show any evidence? Below is a pic someone else posted. My dist doesn't look like that one.

Thanks ultraranger.

Good tips but it didn't mention the that some dist's possibly don't have mechanical advance. I just don't know how an engine could run efficiently w/o it. There's got to be something different about mine. And, I have no reason to believe it's not the original dist for this engine.

I'm no expert but some Fords DID NOT have mechanical advance IIRC. Loadomatic maybe?

Cool, I'll look into the term "Loadomatic".

Willowbilly3, you nailed it! I have a Load-O-Matic distributor. https://fordsix.com/ci/Loadomatic.html

Only problem now, there is "Spark Control Valve" on the carburetor to control the vacuum advance this dist. My carb does not have this valve. There is a provision for it but the mounting port is not drilled nor are there any threads for the valve to thread into.

Another mystery!

From what I've read, the carb and distributor have to match with the load-o-matic. If the carb isn't right, just get a distributor for a non load-omatic. You'll have to do your own search to find what year(s).
Hopefully, someone with more than my vague knowledge will jump in with specifics.

The 2 springs in your pic are part of mechanical advance. The mechanical advance on your Dizzy is just a different style mechanical advance than the 2nd pic. If you take the breaker plate off you will see some weights. There is no other reason for those springs to be there.
Note. I would put those two springs back in the same position when you reassemble it.
