How do you adjust high and low on carburettor

Depending on the type of system you have, carburettor - there is a idle srew near the carb linkages, that you can turn up with the engine running that will adjust the idle. Also if its idling too high sometimes the autochoke could be stuck. If its injection - the idle solenoid could be gunked up. Remove and clean with carb cleaner or petrol then refit. And it will idle high at start then will settle Once engine reaches operating temp. Hope it helps

place the car 3ft from a reflective wall turn the lights on to high beam and adjust using the adjuster screws at the back of the light. Low beam is part of the high beam so when high beam is set then low beam will be correct.

If you have serviced the engine, changed oil and oil filter and air filter and spark plugs and cleaned the carburettor or cleaned your throttle body and injectors, and its still heavy on fuel then try the following. Adjust the carburettor air and fuel. Take off the distributor cap and clean the rotor and spark pionts in the cap of carbon build up by means of light sand paper. Same applies to the spark/ high tension leads and coil lead metal connection points. Check distributor timing as well. If the engine smokes, do a compression test. If results are beneath factory specifications, remove cylinder head, replace the valve stem seals and re-seat the valves and or replace the pistons and piston rings. Basically engine overhall

You must be in neutral at an idle with the brake applied.Then go from low to high. learn more. Facebook Login Sign In Sign Up

The adjustment screws/nuts should be located either on the top of the headlamp assembly, behind the headlamp assembly, or near the frame rail by the radiator support.

You will have vertical adjustment screws for each independent beam (separate highs and separate lows, but will be same screw if highs and lows are the same bulb). You may also have additional horizontal adjustment screws as well

Park your car on a level ground 30 feet from a wall and measure the height from the ground to the bulb and mark on a wall (do this for highs beams and low beams if the bulbs are separate, if highs and lows are the same bulb, only do it for the lows)

For Low Beams: If the headlights read VOR, then aim the brightest part or cutoff part just below the mark on the wall. If it says VOL or nothing, aim them 2 inches below the mark on the wall.

For High Beams (if separate from low beams): Aim the headlight directly at the line you marked on the wall.

Would this be the 1108cc or 1372cc model Uno ? You will find the vacuum advance unit attached to the distributor. Check the pipe connection from the vacuum advance to the carburettor - loose or damaged. This is normally the main cause for uneven idling/stalling. Alternatively the carburettor needs adjustment via the carburettor idling screw. Hopefully this will help. Good luck.
