A float is maladjusted, or is leaking so that it no longer floats properly, causes persistent flooding of the carburettor.Shake it – if fuel splashes inside, it is leaking and must be replaced.If adjustment fails to cure the flooding, that too calls for a new float and a new needle valve.With the carburettor upside-down, measure the height of the bottom of the float (now at the top) above the edge of the body.felt rubber auto oil seals Price reduction.
The height should be 16 to 18mm long for a hollow float or 18.5 to 19.5 mm for a solid float.Adjust the float by bending the tag that touches tho needle valve, or by fitting a thicker or thinner washer under the valve.shaft oil seals.With the carburettor inverted, measure the height of the float above the body edge.Bend the tag to adjust the float height.If the float needle valve is blocked you may have to replace it.felt rubber auto oil seals Price reduction.
Removing the jet
Do not remove the jet of an emission-control model (See Adjusting an emission-control carburettor): a special adjusting tool is needed for its castellated adjuster nut.

Remove a conventional jet by unscrewing the holder, using a spanner on the lower of the two hexagonal parts. Do not move the jet-adjusting screw, as this will alter the mixture (See Adjusting a Stromberg carburettor).
Lift off the jet holder and pull out the jet.

A failed ring will allow petrol to leak from the float chamber.Lever off the ring with a pin or thin screwdriver; take care not to scratch the surface.
