On product delivered after august 2008 there is a remote choke control:
position pushed down is for starting 2, pulled up is position 1 for normal
operation.
The carburettor has an idle adjustment screw (‘D’) which has a tapered
base. This tapered base is upon the carburettors butterfly valve.
Adjustment of the engines idle speed is made by rotation of this screw ‘D’.
Turning the screw into the carburetor will open the butterfly valve inside
the carburettor – increasing the engines idle speed. Screw (‘C’) is the high
RPM fuel mixture screw and is responsible for engine fuel mixture at
engines speeds from around 6,000 rpm and above. Turning this screw (‘C’)
OUT of the carburettor enriches the mixture. The optimum setting for this
screw is between 1 and 2 + 1/2 turns from closed
# NOTE – when closing the fuel screws do so gently – DO NOT seat the
screws hard into the carburettor body, or you will damage the fuel passage
that the screws locate into #
The screw D (idle speed screw) has no effect upon carburettor fuel settings.
