Lada Niva Manual - Maintenance

Every 10.000 Km (and also after the first 2,000-3,000Km if the car is new), wash the carburettor fuel filter andthe fuel pump filter with gasoline and blow them out withcompressed air.Every 20,000 Km clean the carburettor from the inside,wash it with gasoline or benzene and blow out withcompressed air. When cleaning the calibrated orifices ofthe jets, use a wooden stick or match with a pointed endwetted with acetone. Do not use wire, even soft, not todisturb the dimensions and finish of the orifices. Get more news about Carburetor For Lada,you can vist our website!
Whenscrewing the jets in or out, avoid damaging the thread inthe holes.Check and, if necessary, adjust the fuel level in the float chamber and the float travel, forwhich purpose.• Make sure that the mass of float 9 (Fig. 36) complete with arm 7 is 12+1 g, the float has noholes or dents, and can freely rotate on its pin.• Make sure that seat 2 of needle valve 4 is tightened reliably and that damper ball 5 builtinto needle valve 4 does not stick• Set upper body 1 vertically so that the fuel inlet union is directed upwards, the needlevalve is closed, and float tongue 8 lightly contacts the needle valve ball.•

With the parts in this position, measure the distance between the float and the surface ofgasket 10 which fits the upper body; the distance should be 6.5 mm• Change the position of the tongue, if necessary, to obtain the required distance; the tonguemust be perpendicular to the valve axis, and the contacting surface of the tongue shouldhave no defects that may cause sticking of the valve
Every 10.000 Km (and also after the first 2,000-3,000Km if the car is new), adjust the minimum idling speedof the engine. Have this adjustment done at a servicestation. The Owner is allowed only to carry out fineadjustment of the engine idling speed within the rangepermitted by idle speed screw limiting bushing 1 (Fig.37) and by idle mixture screw limiting bushing 2.Attempts to turn the bushings through a larger anglewill destroy them. In this case the Manufacturer bearsno responsibility for excessive content of carbonmonoxide (CO) in the exhaust gases and for excessive fuel consumption.Perform the fine adjustment with the engine warmed-up, valve clearances adjusted, and aspark advance angle set properly. Proceed as follows
