Are you sure all the leads are going to the correct plugs? And the plugs were not hit by accident closing the gap???

86 toyota pick up 2wd carb is idling high

Check for vacuum leaks

You seldom touch any carb adjustments,
there good for years,sometimes decades

I have a 30 year vehicle & only check them every
2 years at inspection time.

Only idles high because you have unmetered air
or vacuum leak or timing is off

sounds like a timing check is required to ensure all is operating correctly when it should.

Ademas de tener encendido aviso de chequea el motor, el carro consume mucho combustible

Sounds like a bad carburetor or missing vacuum lines. Can also be the choke stuck. Clean the carb and tune up the engine. Replace the air filter, spark plugs etc. Give the car a good tune up if you haven't already done so. If this does not help then check the engine compression on all cylinders.

I have a 1991 ford fairmont ea model and we are trying to start it it will turn over but will not start we have changed the fuel pump are you able to help us anr tell us what is wrong.

You need three basic elements for an internal combustion engine to run - spark, fuel, and oxygen. First, pull the distributor cap and check the condition of the rotor button, make certain that the coil wire is in place. This should take care of the spark problem, you should not have to change all the plugs to crank it. Next, since it is turning over check for major vacuum leaks such as the vacuum line running into the brake cylinder. Next, since you changed the fuel pump disconnect the fuel line at the carb and turn the engine over until you have fuel coming through the line, it would also help to change any fuel filters between the carb and the gas tank. Reconnect the fuel line and pour a small amount of fuel directly into the carb. The carb may have set for too long and become dry, this should prime the system. Once it cranks you can fine tune and find out any other small problems such as bad plugs, bad wires, and minor vacuum leaks.

'68 ford mustang with autolite carburetor at idle car runs fine but when excelerating hard car hesitates for a moment then picks up speed normaly. how do i fix this?

Well no computer (Thats a relief) fuel or spark someone getting there a little late. Do a visual inspection of wires, plugs,rotor cap ( if applicable, )points and gaps. Anything that lookjs worn replace. if that doesn't work then do a cylinder balance test just to make sure there are no vacuum leaks. Then take it to a place that does scope testing and they will be able to tell you which one of the wire or plugs is delaying on you.

Technical tuning specifications for a 1997 Toyota Conquest 1300

Don't know about the 97, but I have a 99 escort, 00 corolla, 00 camry and 98 Suburban (though thats diesel so a diffrent animal altogether)... prior to that an 86 and 88 vw quantum and golf respectively... once electronic ignition became standard, there wasn't much "tuning left to do". Change the spark plugs, wires, cap an rotor, pcv valve, air filter, and fuel filter and I think you did a "tune up". With platihnum plugs an such you don't change the plugs often (like once every 5 years or so... depends on the plug, look in your manual). Get the Bosch warranteed wires from a place with lifetime warranty... remember where you bought them..., anything less will fail...

O2 sensors and catalytic converters can be a horror show. Aftermarket replacement catalytic converters cost a few dollars (about 1/3 of dealer cost) but they contain about 1/5th of the metals needed for catalytic conversion, so they fail in about 1 to 2 years... if you plan to keep the vehicle longer, plunk the money down, of you like replacing the things, get the aftermarkets, again a leftime warranty would be a neat trick, O2 sensors - sometimes you can get away with a 35$ universal from the discount shop, I did nonthe vw's, I did not on the toyotas....
