6 Carburettors - general
1 The need to completely overhaul a
carburettor is rare. A carburettor can normally
be kept in good working order if the top cover
is removed and the fuel mopped out of the
fuel bowl. Individual jets can be removed and
blown through. Never probe them with wire or
their calibration will be ruined.
2 Take the opportunity to check the jet sizes
and other components against those listed in
the Specifications in case a previous owner
has substituted some of incorrect calibration.
3 When the stage is reached where the valve
plate spindle bushes have worn, then the
carburettor should be renewed complete.
4 When reassembling the carburettor, use
new gaskets which can be obtained in a repair
pack.
