1 make sure the choke is not sticking 2 see if you can get to mixture adjusting screws toward the base of carb to adjust in.If there are two screws you have to adjust the both of them the same.Do thes a 1/4 turn at a time.
is there a leak in your fuel line, or possibly your fuel filter, if you see raw gas leaking, then it is dangerous for you tio continue to drive it, it only takes one spark to ignite it, however, if the smell is just your car burning rich and the exhaust has holes in it, it will smell up the inside of your car. And yes if your carb. is burning too rich then it needs adjusted. Wasting your fuel, and overloading your engine. I hope some of this was helpfull.
The rich smell is due to too much fuel being drawn through it without enough oxygen to burn it properly. There is an adjustment screw to change the mixture and the advice and specs are in your owner's manual. Jim Hart
I suggest carrying around a small screwdriver for this reason... at all times. My 67 stang had this problem in the Straight 6. There are going to be two adjusters, I honestly say just mess with it until you get an adequate response from the motor that you like. (This is for rough, quick, on the fly moments, like being late for work.) Both will need to be messed with in order for you to get the best burn you can.
1982 ?? their wouldnt be any adjustment as they are fixed jet carbs ,you could try fitting new jets but whats causing them to eat away in the first place i dont know unless its the fuel additive that you have to add to the unleaded fuel
Yes, Colorado is much higher in altitude. Do to higher altitude the barometric pressure is less than sea level by a long shot. Lower barometric pressure mean that less air is entering your engine. Which in turns mean that your engine is now running richer than it was at a a lower altitude. So I recommend checking you engine timing, and adjusting your carbs air/fuel mixture. yes this means that you may need to rejet. but first there is a screw on your 22r's carb that you must adjust to lean the air mixture just right. I have had a stock 22r carbortor before and never had to rejet it. i probibly should have but it ran fine at sea level and all the way to about 10000 ft. after 10000 feet i had to lean the fuel mixture to even alow the engine to run. This screw that you must turn is hidden due to toyota not wanting you to tamper with it and burn your engine to the ground by running your engine to lean. it has a metal plug on the passenger side of the carb about the size of a pencil eraser. you must drill that out and then you can adjust the air fuel mixture. Clock wise is to lean the air fuel. and Counter clock wise is to richen the air fuel mixture.A good rule of thumb is to turn the air/fuel screw all the way clock wise and then back out about 2 and 1/2 turns. That is the factory adjustment. you may only need 2 turns out. Best of luck i hope you get it running perfect. Try this adjustment first then if it still runs rich then think about rejetting.
Here is a picture of what i am talking about.
#1 is the air/fuel mixture, #2 and #3 are cold and warm idle screws. #4 is a A/c idle adjustment.
