1992 jeep wrangler with faulty acceleration. It

Faulty stalk/switch.

Sounds like a problem with the accelerator pump or cruise circuit in the carb. The idle mixture screws only affect the idle circuit.
You start with 2 turns out then adjust it with an exhaust gas analyzer.

That could be a number of things, clogged fuel filter, faulty ignition coil, battery voltage low due to old faulty battery/bad alternator. Recommend finding a reputable mechanic that will properly diagnose the problem.

Yes you can, it will bogg your engine down alot, but you can shift at 30. If possible to wait until you reach 32 33 it would be a little better, but still possible.

did you go with a free flow or cat back system. The wrngler needs back pressure to run properly

how long has this been happing..one tank of fuel or more, could have been bad gas, replace filter,, put gas dryier in fuel tank..if it continues could possibly be transmission related..the reving down doesn't sound like transmission though if tansmission was slipping it would rev up..good luck

You can do either one of two things. Leave the distributor where it is and clamp it down. Or set it up to TDC, mark the dist cap #1 on the housing, lift the distributor and turn the rotor so when it sets back in, the trailing edge (right side) of the rotor is on the left side of your mark. That is how it is base timed. I hope this helps.

the plug of the transmission of 1992 jeep is under the transmission case .

Start by checking the choke. While the hood is up reach in to the carb and give it the gas.If the choke is normal then check your distributor cap for cracks(especially hairline ones,then check your rotor etc.
Best of luck

disconnect exhaust ,muffler or cat may be stopped up
