Carburetor repair (Renault Espace I)

When cleaning the carburetor or disassembling it for repair, replace all sealing gaskets and washers. Clean the inside of the float chamber with gasoline and wipe with a non-lint cloth. When repairing the carburetor, observe the following precautions:

a) Never clean the jet channels or other openings with needles, wire, etc., as this may disrupt the calibration.

b) When replacing a jet, always install a jet of the same diameter. Installing a jet of a larger diameter on an engine does not increase performance, acceleration, etc., if the other jets are also not changed. The desired results can only be achieved by testing the engine on a test bench.

c) When replacing carburetor parts, use only those recommended by the manufacturer.

d) Do not handle aluminum parts with sharp objects. Do not apply too much force when tightening bolts. Before tightening bolts, make sure that they are exactly in the screw holes. Aluminum threads are easy to strip, and an incompletely sealed surface allows air to enter, which affects idle speed.

e) Use only a screwdriver with a sharp blade to unscrew the jets. The jet channels must not be damaged.

j) When removing the float, do not deform its tongue, as this affects the installation of the float. Put the float aside in a separate place. To check the needle valve, push the valve into the seat and blow through the fuel supply pipe. Air should not pass. After releasing the valve, air should pass freely.
