How many times do you wind out the mixture screws to give you best fuel economy on a 350 holly?
The initial setting for the mixture screws is 1 1/2 turns out. Connect a vacuum gauge and turn them until you get the highest reading and make sure they are both set the same. This will give you the best fuel economy.
How do you adjust three cylinder gasoline engine carburetor?

If the car is carbureted then there are two little screws on the carburetor called air/fuel mixture screws that control the air/fuel mixture. There should be info. on your cars factory settings. Hope this helps.
Does the holley 4160 have two air-fuel ratio screws?
Yes, it should. They are located on the lower front section of the carburator. These screws will only adjust the air/fuel ratio at idle. *On a holley 4160 vaccum secondary carb, the mixture screws are on the front metering block on each side. The transition slot to throttle blade relationship has to set/corrected before the mixture screws will be effective.
How do you adjust the carburetor on a featherlite fl20 weedeater?
The idle speed of the carburetor on a featherlite fl20 weedeater can be adjusted by turning the small screw that is located right next to the choke setting switch. For the best adjustment, the featherlite should be on and running. If the weedeater is running rough, the mixture can be adjusted with the low and high (labeled L and H) mixture tamper proof screws.

FUEL MIXTURE SCREW ADJUSTMENT PROCEDUREThe fuel mixture screws control fuel. They are used in conjunction with all of the carbs other jets to allow a means to compensate for differences in seasonal temperature, and geographical locations.Like a general rule turning the screws in restricts fuel giving learner mixtures at idle and in the cruising mode. This can be useful when operating in hot weather or high altitudes.Turning the screws out increases fuel flow giving richer mixtures which can improve cold weather operation.You must do these adjustment procedure with your carbs previously synchronizedWell, first of all, where are they?... in our FJ they are at the top of the carbs body. See the photo. Each screw must be covered by a little plug, but it could be a lot of FJ without them (like mine). In FJ European models you can take the plugs out with a little screwdriver, but in Usa FJ types you must use a drill very carefully to extract them.Basic Yamaha base settings: FJ 1100 & 1200 until 91: 2 turns out from fully closedFJ 1200 from 91: 3 turns out from fully closed1.- Start taking the fuel tank out in you FJ 1100 model and plug the vacuum line that is attached to the tank and use a alternative fuel tank or fit longer fuel lines to position your tank in a better place to get access to the screws. 88-90 models only turn 180º the deposit like at the photo. The rest of you... well, I don't know, but the rule is to get access to the screws maintaining a fuel supply. (Infos at this point are welcome)2.- Check that the pilot screw are positioned at their base settings.CAUTION The fuel mixture screws are easily damaged by careless adjustment. If you turn the screws in and do not stop when it seats lightly, you can break the metering tip off. Sometimes the screws may be tight in the threads and if you are careless by the time you find it out the screw slot is rubbed off.The best procedure is to get a screw driver with good sharp edges that fit the slot closely. Then turn the screws in first about 1/2 of a turn. Now, blow out any metal shavings or crude. Next put in a few drops of penetrating or light oil. Then turn the screws out a couple of turns and back in, to make sure they move free. Now turn the screws in until they seat *lightly* then turn them out the number of turns given as the base setting3.- Warm the engine up to normal operating temperatureAt this point, previously I have synchronized the carbs. But don't leave the motor gets too hot.4.- Set the idle down to approximately 500 rpm. The best method for setting the mixture screws is using the "Blip the Throttle" test. Start with the mixture screws set at 2-1/2 turns out and blip the throttle. Pay attention to how the engine RPM returns to the initial idle speed. If the mixture is rich, the engine speed will "hang up" and slowly return to idle speed, and if the mixture is lean, the idle will drop quickly, then slowly recover to the correct speed5.- Adjust the mixture screws within 1-1/2 turns either way of the base setting to attain the smoothest and fastest idle. If the idle speed increases after setting any screw, reset the idle to around 500 rpm before going to the next carb. The full mixture screws do not have to be at the same settings as long as each setting is the best running setting for that carb.6.- Go carb by carb: adjust 1/2 turn out in ome carb. If the idle raises, reset the idle again to around 500 rpm and go 1/2 turn out. Repeat the procedure until the idle drops. Then go back at the setting before this one. leave this carb at the setting obtained and go for the next.My screws have finished with around 4 turns out all of them. Think that my exhaust are a Race type one, with no restriction at all.7.- Reset idle to factory specifications.8.- Switch the engine off and replace the fuel tank.I think this is not a difficult task and cheap too. Other ways is to use a gas analyzer attached to the original collectors fittings (very expensive) or use a Colour-tune. It replace the plug and show if the mixture is lean or rich changing its colour. I have not tested, but I have read great reviews.
Where are the airfuel mixture screws on an 87 prelude?

Is the Air fuel mixture screw on a 2004 TXR 90 Honda air or fuel screw And what is the factory setting?
Cant say from experience with this particular model whether it is an air or fuel screw, however; If there is only one screw then it does both. If there are 2 others near it then one does the air, the other two do the fuel. The factory standard setting for the main idle-adjustment screw on most bikes is 1 and 1half turns out from closed position. This is often the case with the other adjuster screws as well, but the mixture will need to be altered as the engine wears.
