Hi, was member 5 years ago, sold that car. Back with another Zephyr. This one is a challenge. :bang: Couldn't resist for $175.
It runs good until the floats sink. lol. 1946 carb has many issues and not rebuildable.
The only usable bolt-on carb at pull-a-part was a YF(A?) from a '77 Econoline/300 c.i.
I bolted it on the car yesterday and it idled fine, but had no acceleration, I'm hoping it's just a bad accel pump diaphram?
Also didn't feel any vacuum from the 3 ports? wrong base gasket?

I'm going to de-smog the engine also.(remove the EGR valve/plumbing). then sort out whats left of vacuum hoses.

Q: will it be difficult to tune the YF to operate properly on the smaller engine?

Q: YF has 3 vacuum connections= one at the base(says EGR next to it), one at mid height on driver side and one in airhorn.
Which of the lower two should I use for the distributor?

Thanks for the HELP! Bill
 
Mid-height port will be venturi vacuum, by the sound of things. What was your old username?
 
Hi Bill

I'm running a YF from a '75 300 on my warmed-over 200. It works great with the stock jetting.....very good performance and is getting 24-25 mpg average in the Falcon. I am running manifold vac to the distributor-right off the intake manifold below the carb. I believe addo's correct on the mid-height port being ported (venturi) vacuum.

Hey "Zephyr" good to see you back. Lots of changes since you were here last. Anyway, just wanted to say "Welcome Back".

you hsouldnt have gone away in the first place....

I know, I'm a bad man for selling the first Zephyr... :oopsie:
I liked it enough to drive it with no reverse for 6+ months. :deadhorse:

This forum is more fun than the last one I was on!!
 
Simple carb rebuild :roll: has turned into a real PITA. :bang: :fume:

While putting carb on, realized that one holdown nut vanished from the toolbox... no spares of course.

Noticed the vacuum fitting on the manifold was loose, while attemping to loosen the hard line to the MC the fitting separated from the intake leaving threads in manifold...

When that broke, bumped the EGR pipe from exhaust manifold outlet and that broke off at the fitting... (was 99% rusted through)

EGR plate between intake and carb bolts were loose, so removed bolts to check gasket and that EGR pipe also broke...

I was planning to remove egr anyway, but LATER at my convenience.
Now I'm modifying EGR manifold plate and the vacuum fitting and having the EGR exhaust manifold fittings welded, since no "plugs" exist for those holes. Then of course will have to sort out left over vacuum lines... WHEN WILL IT END? :shock: I just wanted to drive it

I don't know how to post pictures on here, but have a cardomain site with a few pics of car. (link in signature)
Poor thing has been abused and neglected for a long time before me, hopefully I can rescue it and keep it happy for a while :wink: Bill

I got plugs for mine. :)
 
JackFish, nevermind my last post, the fittings are seized solid in the exhaust manifold! :evil:

Modified EGR plate :D

Oval area was inlet from EGR valve, now filled with JB Weld. :wink:

repaired/modified manifold vacuum outlet.

Carb is rebuilt and static adjusted, scored new hold down nuts at work.
That's four out of five issues handled!
 
floats sinking due to holes? Put JB weld on the holes after they're emptied of gas completely and dry. Let sit overnight. Don't adjust them, reinstall them in the carb. It will run flawlessly if that's the only problem. =D
