Checking the technical condition and repairing the carburetor (VAZ-2105)

After disassembling, wash all parts in gasoline, blow with compressed air and check their technical condition. The sealing surfaces must not be damaged, the warping of the planes is allowed no more than 0.2 mm. Body parts (carburetor body, cover, throttle body) must not have breaks or cracks, thread stripping in the holes is not allowed. Replace damaged parts with new ones.

The needle valve should move freely in the seat, not have wear, and the damper ball should move freely and not hang. The tightness of the metal float is checked in a bath with heated water. The weight of the metal float of the 2105-1107010 and 2107-1107010 carburetors should be 11-13 g. Replace damaged parts with new ones.

Clean the channels and emulsion tubes with special reamers. Clean the jets from resinous deposits with acetone or gasoline. Check the jet capacity and compare them with the reference ones. It is not recommended to clean the jets with a metal tool. If they are heavily clogged, clean them with a soft wood needle soaked in acetone. To avoid clogging the emulsion channels, do not wipe the carburetor parts with cotton wool or rags. Blow the channels with compressed air in the direction opposite to the direction of movement of the fuel-air emulsion.

The diaphragms of the starting devices and economizer must not have any tears. For carburetors 2105-1107010 and 2107-1107010, check the reliability of the flaring of the starting device rod. The size of the starting device spring must be at least 17.8 mm. Otherwise, replace the parts with new ones.
