ts my first bronco ive had and was searching on here for a thread like it and
all i found was what was your favorite/least favorite. I like thinking of stuff
on my own vehicles ive had but its nice seeing what others have done to
and branching off tge idea and doung it your own way or following how they
did it.
x2
That's the key to it IMO, check out how someone else did it then "improve"
on their idea/s when you can.
Like Steve's clocking of his transfer case
and how any of us could clock ours better because we got his "mistake" to
work off of and his huge picture to boot. LOL
Thanks, Steve.

I just now noticed you got a '81 so here's a couple carburetor ideas...
The hole in the throttle rod is not a ball shape but just a drilled hole so a
cylinder shaped stud will actually wear less and spin in the hole with less
friction. This is a smoothed up Allen head screw... (they're grade-8)
Lots of guy have gone with Heim joints, those are cool and all but they're
expensive and I've noticed they break easy both. That's just been my
experience is all, from my dune buggie days.
In that same picture is my new spring seat that I'm kinda proud of. LOL
Hey, the spring rubs on brass now!
Ok, so I'm easily entertained. :/
Just another view...
I can't remember which holes I tapped to 10-32 or not but did it that way
where I could.
{used a de-burring wheel to smooth up the screw head like it is}
{you don't need to do that.}
-----------------------------
These old Ford carburetors are famous for hesitation and stumbling, many
were thrown away for it and the fix is simple and works great! Most guys
will just increase the accelerator-pump-shot as a band-aid but sure-as-heck
>ain't< the fix or the cause of the problem!
No kidding.
The cause of the problem is the "low speed circuit" is too lean in many but
not all of the carburetors effected. Another fault of these carburetors is
Ford used two different types of emulsion tubes, one ain't so good and the
other kicks butt.
I'd sure like to take a better picture, but here's a picture...
^That thing's called a "venturi booster assembly" I recommend you don't
take yours apart but instead correct your booster assembly while it's still
assembled. Another trick is to find a booster assembly that's got the right
emulsion tubes in it and use/start with it.
The long skinny brass tube laying there has got the low speed circuit's jet
squeezed into its tip, it's long/low like that to pick up fuel. The hole in the
tip needs to be reamed out just a little bit if your carburetor stumbles right
off idle.
In the old days I used gas torch cleaners now I got jet reamers. xD
You don't need anything that exacting just increase the size a little bit and
try it out.
{make them the same size tho}
Poor performance just above the low speed circuit's air flow is where you'll
notice the crummy type emulsion tube not being the better type. The better
type has 8 holes all along the sides like the two installed emulsion tubes
shown.
The crummy type's got all 8 holes up around the top. Solder 6 of those holes
shut and drill 6 new holes down the sides. Make the new holes the same
size as the original holes. Do these by hand don't use a Dremel.
That is cheaper than buying a new carburetor huh? And the new carburetor
ain't guaranteed to be any better than the old carburetor!
Lots of places tell you how to (main) "jet" a carburetor so i won't go into
that here.
