GENERAL NOTES ON INSTALLATION

a. It is preferable where possible to fit the throttle levers supplied to the carburettors before installation, and ensure that the throttles open and close freely prior to connecting the throttle linkage.

LINKAGE ASSEMBLY INSTALLATIONS

g. Remove the two centre top cover screws from the left hand carburettor. Fit the
Actuating Linkage Bracket (5A) and secure using the 2 x M5 Screws (6) and 2 x
5mm Spring Washers (7), see Fig. 1.

h. Fit the Adjustable Eyelet (8) with the M8 Nut (9), Plain Washer (10) and Lock Washer
(11) to the Actuating Quadrant (5B), see Fig 2.

i. Connect the Actuating Quadrant (5B) to the Linkage Bracket (5A) with the 35mm
Pivot Pin (12) and secure using 2x R-Clips (13) and Plain Washers (14), see Fig. 3.

j. Connect the Linkage Rod (15) between the Adjustable Eyelet (8) of the Actuating
Quadrant (5B) and the Male Throttle Lever (1).

k. Insert the 27mm Spring Anchor Pin (16) to the Linkage Bracket (5A), then place the
2 x Throttle Return Springs (17) onto the Pin (16) and secure with the remaining 2x R-Clips (13), see Fig.4

l. Insert the 48mm Threaded Pin (18) into the Actuating Quadrant (5B). Place
2 x Plain 6mm Washers (19) onto the Pin (18) before attaching the
2 x Throttle Return Springs (17), see Fig. 4

m. Remove the two centre top cover screws from the right hand carburettor. Fit the Cable
Anchor Bracket (5C) and secure using the remaining 2 x M5 Screws (6) and 2 x 5mm
Spring Washers (7). Fit the 2 x Cable Adjusters (20) into the Cable Anchor Bracket
(5C) to approximately 2/3rd of the thread length, see Fig. 5.

ACCELERATOR CABLE CONNECTION

n. Fit the Accelerator Cable Connector Block (21) provided to the accelerator pedal at a
position to be able to achieve an accelerator cable operating movement (pull) of
between 30mm and 40mm.

o. The Accelerator Cables (22) must now be secured in a suitable position to align
correctly with the Connector Block (21). This can often be achieved by drilling two
6.5mm dia. anchorage holes 20mm apart in the engine compartment bulkhead. Fit the
remaining 2 x Cable Adjusters (20) to form the anchorage for the accelerator cables,
secure the Cable Adjusters (20) using the 4 x M6 Nuts (23) and 4 x 6mm Support
Washers (24) provided.
N.B. It is important to ensure that the cable alignment is correct throughout the full
movement of the throttle pedal, and does not allow the accelerator inner cables to
misalign with the Cable Adjusters. Failure to do so will result in poor throttle
operation and wear to the accelerator inner cable which will ultimately cause a
breakage.

p. Fit the Accelerator Cables (22) by first removing the inner cable from the outer cable.
Route the Accelerator Outer Cable between the Throttle Linkage Anchor Bracket
(5C) and the Cable Adjusters (20) (at the Throttle pedal end).
Where necessary cut the accelerator outer cable to achieve the best cable route
between the anchorage points, support and secure the cable as necessary using the
Nylon Ties (25) provided.
N.B. It is very important to avoid tight bends, moving components and heat
sources.

q. The inner cables can now be threaded through the throttle pedal Connector Block (21) - see Fig 6. Pass the inner cable through the accelerator outer cable anchorage Cable
Adjusters (20). When the inner throttle cable is fully inserted the barrel ends of the
inner cable will abut the Connector Block (21). Lightly secure the inner cable to the
Connector Block using a 2.5mm Allen Key, do not over tighten. The inner cable should
now exit the outer cable at the Cable Anchor Bracket (5C).

r. The accelerator inner cables can now be threaded through the hole in the Threaded
Pin (18) of the Actuating Quadrant (5B), having first placed 2 x M6 Nuts (23) followed
by 2 x Plain 6mm Washers (19) onto the Pin (18). Next place the remaining 2 x Plain
6mm Washers (19) followed by the remaining 2 x M6 Nuts (23) onto the Pin (18). With
the accelerator inner cable between the plain washers and the M6 Nuts (23) ensure the
inner cable remains central in relation to the hole in the Pin (18) but do not tighten until
operation t. in the ACCELERATOR CABLE / LINKAGE ADJUSTMENT.

ACCELERATOR CABLE / LINKAGE ADJUSTMENT

s. First determine the required height of the throttle pedal at the throttle closed position.
N.B. This will be predetermined if the throttle pedal has a return spring and the stop may or
may not be adjustable.

t. With the throttle pedal in the throttle closed position clamp the accelerator inner cable in
the linkage Pin (18). If the throttle pedal has a return spring, allow a small amount of
free play in the accelerator inner cable.

u. The throttle linkage can now be adjusted achieve full throttle by adjusting the
Adjustable Eyelet (8) of the Actuating Quadrant (5B).
Important: In the full throttle position the throttle pedal should contact either an
adjustable pedal stop or the bulkhead. This will prevent excessive pedal force from
damaging the Carburettor, Throttle Linkage or the Accelerator Inner cables.

v. Finally make any fine adjustments to the Cable Adjusters (20) in association with the
Adjustable Eyelet (8) with regards to full throttle and ensure a small amount of free
play exists in the accelerator inner cable where the throttle pedal has a return spring
with a top stop.

NOTE: IT IS THE RESPONSIBILITY OF THE INSTALLER TO ENSURE THAT THIS
LINKAGE IS ADJUSTED AND FUNCTIONS CORRECTLY, AND THAT THE
ADJUSTABLE EYELET (8) OF THE ACTUATING QUADRANT (5B) CANNOT BECOME
IN-LINE WITH THE LINK ROD (15) AT FULL THROTTLE AS THIS COULD CAUSE THE
THROTTLE TO JAM WIDE OPEN.
