Throttle cable hitting air filter - Sticking

[lawnmower00]

Hi Everyone!

When I pressed my gas peddle I noticed it sticking sometimes... I looked under the hood (the bronco is newish to me) and noticed the throttle catches on the bottom of the air filter. AND THEN, I noticed a tie-wrap on the throttle linkage...

Any fixes for the air filter? A certain type that may work better?

And what the heck is that tie wrap there for?!?

Please help

Hi, you have an old Carter AFB.
They are now Edelbrock AFB carbs.
I think the linkage is hitting the bottom of the air cleaner.
Probably a different style air cleaner could fix that.
You could drive a little with no air cleaner to test that.
It looks like the cable tie is holding the automatic transmission kick down lever. You must have a stick shift or you would need to hook that up.
Good luck

Thanks for the reply!

It is an auto with the C4 - so this tie wrap is making it so it can downshift?

Sorry if that’s a stupid question!

Any air filters setups people recommend?

The tie wrap is there because parts are missing and it keeps park of the kickdown from flopping around. The tie wrap shoule NOT be there. There should be a rod going from the throttle linkage to the transmission. So full throttle it will force a downshift. My '77 F250 (as a reference point) would shift at 2500RPM at full throttle without the linkage but with the linkage it would shift at 4000 RPM. A lot of performance is lost if you don't have that 2500 to 4000 RPM window. Someone was a lazy hack while working on the Bronco sometime in the past.

As for the air cleaner, it is some random aftermarket piece. Doesn't even have the correct element in it (too small). Recomending one is difficult, there is always this balancing act of clearing the carb, clearing the hood, clearing the distributor, not cleaning out the wallet. I've even had to go to the trouble of getting a drop base air cleaner housing then having to put an air filter spacer under it to get stuff to fit. What works for someone may or may not work for someone else.

Hi, you should try to find the kick down linkage or your engine will lug after you slow down and the RPM s are really too low for the tranny to work right.
If you have a speed shop like parts store nearby maybe they can recommend and air cleaner.
Edelbrock style carb so maybe an Edelbrock air cleaner.
Try driving with out it .
Good luck

Maybe a little ball peen clearance tool is in order. Ken

I was thinking a little motivation to the air cleaner too
A junk yard would be a breast place to source those parts
Find a correct throttle linkage diagram and go from there

When you hit the gas the the Tehran’s downshift pretty quickly

This Bronco has had many finds of a lazy hack... haha. Mysteries abound everywhere. Is there a difference between getting a rod or a cable? Is there a certain kit you'd suggest? Thanks again for your help!

I'll definitely go hit up a junk yard in a couple of weeks!

That would be an effective temporary fix
