How to adjust the fuel and air mixture on a 1982 ford 4.9 six cylinder, carter carburetor.


There should only be 1 screw located at the base of the carb facing outward.

The method I use requires a tachometer. If you don't have a tachometer then you can use the "by ear" method, though it's not as accurate.

With the engine off, start by turning the screw all the way in, then back it out 1 and 1/2 turns. This usually give you a baseline to start with.

Start the engine and get it up to operating temperature, make sure the choke is fully open, and have the air cleaner and all vacuum lines installed.

Using the tachometer (or ear) turn the screw (usually out) until the RPMs increase. If they don't increase by turning the screw out, then try turning it in.

Eventually the RPMs will stop climbing while turning the screw (as said earlier, usually out).

THEN turn the screw the opposite direction (usually in) until the RPMs JUST start to drop off. That should be real close to the optimum setting.

This setting is ONLY for the base idle air/fuel mixture and is NOT for anything else.

Hope this helps.

I have a 1982 yamaha vision 550 i have it runnin but hard to find a smooth idle choke to high idle real fast choke to low it dies


Hi, Renee and the usual suspects are:
1. Fuel cap or fuel tank is not venting properly.
2. Fuel filter clogged.
3. Fuel line pinched or kinked.
4. Float needle and seat sticking.
5. Float level too low.
6. Carburetor bowl vent line clogged/blocked/pinched.
7. Idle adjusting screw set too low.
8. Air/fuel mixture screw set too lean.
9. Idle port, transfer ports, slow air jet clogged.
10. Slow fuel jet clogged.
11. Faulty fuel pump.

My 1998 Honda Shadow ACE 750 backfires alot when i let off the throttle. What causes this?


Sounds like your fuel air mixture is a little rich. Check your plugs, if they are black you are running rich which will cause some of the excess fuel to be burned off in your exhaust. Two common problems with a bikes fuel air mixture is bad plugs, if one does not fire consistently all the time it will leave excess fuel in the combustion chamber. Another would be a clogged air filter keeping the fuel air mixture unbalanced as well.

Lastly if you are able to, you may adjust your air fuel screws on your carb. However most Honda's are stock with Keihin carburetors and these air fuel screws are plugged so you cannot make adjustments without drilling out the plugs.

1982 honda cm250c wont stay running


Sounds like fuel supply problem.Take the carburetor apart and clean it thorough especially the pilot screw (use new o-ring) and the idle jet should be perfect cleaned.Check your rubber insulator where the carburetor plugs on to if it has any cracks and draws extra air in the mixture.

I just bought a 2000 Honda Shadow Sabre 1100. It appears to be "running rich" and friends have said I should adjust the throttle/idle. How do I do this??? Thanks


To adjust your idle speed there is a single screw (usually with a black plastic knob ) that hangs down between the two carburetors. Turning the knob will raise or lower the idle speed. Clockwise will raise the idle. Counter clockwise will lower the idle. Changing the idle speed will not lean or richen the mixture. To change the mixture you will have to rejet the carburetors. I assume the carburetors have been rejetted to compensate for an after market exhaust system. In which case the carburetors are set too rich (too big of a main jet size) to compensate for a bad flat spot in the acceleration. If this is the case, take out the main jets and replace them with the next smaller size. If the machine is stock then check your air cleaner. If it is restricted/dirty, then the extra vacuum caused by the dirty air filter is causing the rich mixture. Try changing the air filter or in stall a high flow air filter like a K&N. This will put the mixture back to normal.

I TOUCH THE CARBURATOR OF MY SON TTR 50.. WHAT CAN I DO TO PUT BACK STOCK SETTING...???


the carburetor settings are easy : 1- locate the screw mixture air /fuel 2- wind the screw all the way in 3- unwind the screw 1 1/2 turn and this should be sufficient to set the carburetor back to its original settings for the air/fuel mixture . 4- as for the idling screw , wind it down to suit the revs required

I just rebuilt the carbs on my 1982 goldwing interstate and now it is blowing white smoke out of the right side exhaust


Hi, P_cameron001 your instrument gauges and lights can alert you to most electrical and engine issues they can not warn you about failed engine gaskets or seals so your engine has to resort to old fashion alert methods of colored "SMOKE SIGNALS" here is a breakdown of their meaning:
1. COLORLESS OR SLIGHTLY BLUE SMOKE on start-up means your air/fuel mixture is at the right composition and everything is well burnt in your combustion chamber.
2. BLUE SMOKE on start-up is usually caused by failed valve seals dripping oil into the combustion chamber when the engine is not running.
3. YELLOW OR BROWNISH SMOKE at start-up means your air/fuel mixture is too lean. Too lean means that there is low fuel but high air mixture in your combustion chamber.
4. WHITE SMOKE on start-up may be caused by a blown head gasket allowing coolant to enter the combustion chamber and may start dripping out of the exhaust pipes or mufflers. Smoke while riding is usually caused by worn out or damaged valves, seals, guides, pistons, rings, or cylinder walls.
5. BLACK SMOKE on start-up is usually caused by too much fuel in the combustion chamber this can be due to air/fuel mixture adjustment too rich, accelerator pump improperly adjusted, faulty choke/enrichner or not in the off position, air filter dirty and clogged, faulty carburetor float needle and seat, pilot jet too large, fuel injectors leaking, smoke while riding is usually caused by the main jet being too large or a damaged carburetor.
It should be noted that aggressive or abnormal throttle operation will cause these conditions to manifest themselves exponentially.

2008 Honda VT 750 Shadow Aero carburetor adjustment


Hi, Rockin_hick1 you need to make sure you have no intake leaks by spraying some Brake Kleen, Contact Cleaner, Starting Fluid etc. around the intake manifold and seals, if the RPM's go up or down significantly then you have a leak that needs to be fixed before you can continue with the carburetor adjustment.
The engine should be at operating temperature with the enrichener off to set the idle between 950-1050 rpm. Turn the idle skrew clockwise to increase the idle speed and counterclockwise to decrease the idle speed. If you have access to your air fuel mixture skrew you may turn it as well, if not there is a video below on how to gain access, make sure you start with clean or new spark plugs. Gently turn the air fuel mixture skrew clockwise until it starts to bottom out "STOP" do not over tighten as it will damage the taper on the end, now back the skrew out 1-1/2 full turns to establish a starting point start the engine and check the idle rpm's and turn the idle skrew accordingly for 950-1050 rpm if necessary, turn the air fuel mixture skrew 1/4 turn at a time and let the engine settle for about 10 seconds, turn the skrew clockwise for a leaner mixture and counterclockwise for a richer mixture, you are seeking the highest rpm your air fuel mixture skrew can acquire without going past 3 full turns from bottom then resetting the idle skrew back down to 950-1050 rpm If you can not detect any rpm change and can not stall the engine by turning the air-fuel mixture skrew all the way in then your pilot/low-speed jet is too big and needs to be replaced with the next size smaller. Final adjustment should be made with a clean air filter mounted to the carburetor.
