The throttle body on those carburetors does NOT use a bushing for the throttle shaft. They are single-use only, and not serviced separately. You may be able to find a replacement throttle body, as they were available in their parts system at one point, but that was decades ago.

My 1988 Chevy s10 2.8 4 cylinder starts out on real high and dies when you go to give it gas

So it may be a lack of fuel, or a vacuum leak causing too much air to enter the system. This would cause high rpms. When you "give it gas", you are actualyy opening the throttle body which lets more air in and kills the engine. I would replace the fuel filter and tnen check for a vacuum leak by spraying carb cleaner around the vacuum hoses and listening for a change in engine rpms. There are numerous vids on how to find a vacuum leak.

some of your new parts might be manufacture defected because the manufacture does not test every part coming from the lines. ANother thing have you checked the timing out with a timing gun to see if the timing is ok ? ANother also did you replace the new dist. cap and button in the right place of the old one was at ? Sometimes when you change some things with your car that you also have to check for timing issues because where and how you put the dist. cap and button at if not the way of the old one was. It could be off alittle bit to make this happen.

UIs the check engine light on? if so what codes are showing, if you dont have a code scanner, have it scanned for free at an Auto Zone Parts Store, or Discount Auto, etc., they will decipher what the codes are for you tell you what and where the defective parts are and give you a parts price estimate and availability.
It sounds like a defective/sticking Idle Air Control Motor(IAC) or a sticking throttle blade or linkage at the throttle body base.
Before anything try to observe by eye anything that appears to look defective, broken or misaligned, such as a broken throttle linkage return spring or the like.
Also apply a good spraying over all the movable linkage parts with WD 40 or its counter part product of your choice.
Hope this info helps.
Happy Motoring!!

That carburator most likely has vacuum secondaries, meaning that the secondaries won't open until there is enough vacuum for them to operate, usually mid or full throttle. You can try to operate them by hand to confirm that the shaft isn't stuck.

Need adjustments for 88 model carter 2 barrel carburator. fits 4.2 jeep

To set carb adjustment, first set timing correctly, then put both a vacuum gauge and tach on the engine. adjust one idle screw to highest vacuum reading and highest tach reading, then do the other one. go back to the first and re-adjust again, then the other. I find that if you have a mechanical screw or a solenoid that holds idle speed on the linkage, turn them back so that engine is idling at the lowest possible rpm without stalling before making adjustments, then when finished, bring idle rpm up to recommended rpm using those. On an older carb, usually the idle screw covers have already been removed. If not, you need to remove them before you begin, usually best done with carb on a bench.

hello if this is carburated look inside the carburator front inside at the wall look for crack or cracks on the inner walls check all hoses for cracks dried rubber you can usually find exterior vacuum leaks with a can of carb cleaner lightly spraying around base of carb but extreme caution has to be taken when doing if your not that experienced i wouldnt advise this if your car is equiped with tps sensor check for possible out of range sensor goodluck

Too fast idle

what can be happening and is a common issue is that the pedal return spring on the throttle body (linkage) gets weak over the years it happened to mine 2 months ago so u just want to make it tighter by winding it around one more time and lubricate the whole linkage
