My honda civic manual carburator is not properly working. it won't start if you will not step on the gas. what should be the problem? idling is also not balance.

I would check the computer for codes first.

Check if there is a lag in the needle of the tachometer when you step on the gas when in gear and when in idle. If there is no lag or anything unusual while the engine idles, it may be the transmission. It may be the clutch for manual transmission or the torque converter for the automatic or you may need to add or replace transmission fluids.

I would start with adjusting your idle speed.

I AM LOOKING AT A STOPPED UP FUEL FILTER.IDLE SPEED CONTROL NOT WORKING.WATER IN GAS.LOOSE WIRE IN THE IGNITION COIL.

try chage the gas filter i had the same problem and when i chaged the filter it fixed everything

the idle air control valve usually takes over the idle after coming to a stop with no gas being given by the driver if it is not working properly the car will not idle at all this is probably what the problem is

sounds like airflow problem. try blow air and spray carburator cleaner to clear the passages from all ports leading to/coming out from the plenum. check EGR port for carbon buildup.

Several causes possible.
Carburattor or injection type?
Carburator >> auto choke faulty.
Carburator >> mixture very wrong adjusted
Drawning carburator (needle/floater)
Distributor weights cannot move (dirt/rust spring broken)
Very dirty airfilter, or clogged airfilter
Faulty ignition cap. Check contacts, especially middle one if oldfashioned and nonelectronical.
Ignition timing set incorrectly.
Fuel pump broken.
Fuel filter blocked almost.
Vacuum line damaged.
Exhaust internally clogged by loose plate (corrossion) (potato in tailpipe effect).
And very seldom, water or diesel.

And a list of a lot of other things.

if your car turn over and it sound like it want to start then i think it is your ignition coil so got car scrap yard get another that is your vehicle and put it in.

I dont know where do you live, but honda civic 1992 don use carburator, they are fuel injection, you can have coolant temp sensor problem, or map sensor problem, run diagnose jumping the diagnose wires loated in the passenger side, kick panell close to the door wall, better get the repair book in the parts store to locate the conector ,and read how you can run the diagnosis
