posted a question of adjusting the carb, unfortunately i didn't tell u guys it was the carb....SORRY!

anyways, got a new question

on the passenger side door with the little window that you can swing out, it squeals so bad when i am goin fast, any ideas? givin me a headache

also, back to the carb, how do i adjust the fast idle? won't kick down after warmed up, 83 bronc 302 2v carb

 

did u rebuild the carb? buy a new one? what is the situation w/that?

has your wind wing ever get broken into? it probably isnt closing or sealing all the way. or maybe you shouldnt go fast which is not that easy if you have a lead foot.

 

carb was rebuilt with engine, the guy who had it in arizona disconnected a bunch of stuff that i have redone, just don't know how to adjust everything correctly

what i meant by goin fast was on the highway dude, at highway speeds it squeals really loud, what is the wind wing?

 

Replace the weatherstrip around the vent window. that should solve your problem.

In the meantime, look for any rips or gaps in the weatherstripping and fill them the best you can with black silicone. When it is dry (or right away, if you don't have any rips) soak a rag with some WD-40, open the vent window, and work the oil into the weatherstrip and then close it tightly. This will help it to seal.

For the idle (assuming that it is simply set too high) , there should be a screw that the linkage rests against at idle. If you can't find it, remove the breather and move the linkage by hand. When you move the linkage back to the original position, where it touches the piece that stops it, that piece should have a screw in it. the end of the screw makes contact with the linkage and stops it. So if you back the screw out, it closes a little further and the idle lowers; threading the screw in pushes it up and raises the idle.

Not positive what sort of carb you have, but that is how you adjust the idle on most carburetors.

If it is a choke problem, that's usually just sticky linkage. Check that the choke linkage moves freely. Spray some carb cleaner all over the linkage. The choke idle can also be adjusted. Again, I do not know what type of carb you have. On many of them, there is a black circle that is held in place with 2 or 3 screws around the edge of the circle. Loosen the screw enough that you can _just_ move the circle, (alternately, have someone in the truck start it while you hold the loose part still). Start the truck from a cold start, cold enough to activate the choke. Once the truck settles into its fast choke idle, move the black circle to adjust the fast idle speed, and tighten it up when it is right. Then watch to see if it drops down to regular idle after it warms up.

There are lots of different types of carbs - yours may have different adjustments (especially for the choke) but those work for most American carburetors. There is also a thermal sensor for the choke - simply a piece of metal that expands and contracts. That is how the choke knows when the temperature is warm enough to stop choking. If that thermal sensor goes bad, the choke either won't wprk, or it will stay choked and idle high and run rich - killing gas mileage.

The best thing to do is to make your adjustments and then observe the choke on a cold start to see what is happening.

It's sort of hard to explain this - it's a lot easier when you are looking at it. It is not complicated.

 

The window question can be temporarily remedied by putting a nickel, quarter, whatever between the latch and the post to pull the window tighter against the gasket until you can replace it.
