 After a hole was drilled in each side of both carburettors, they were painted in the
same manner as the gearbox. Model Car Garage photo-etched metal throttle linkage
details, and wire, were used to make the accelerator cable and throttle return springs. The
latter were made by winding wire around a pin.

 For ease of assembly and to reduce handling the carburettors, a jig was made to
build the throttle connections. The rear carburettor bracket required three holes (for the
accelerator cable, throttle return spring and linkage), whereas the front carburettor bracket
required two (linkage and throttle return spring).

 After the pins were trimmed to length, the completed throttle connection assembly
was glued with epoxy into the carburettors. The latter were then attached with gel CA; the
throttle return springs were inserted into holes in the intake manifold as the assembly was
lowered onto the engine. Excess wire was then trimmed.

 The fuel lines were bent to shape and cut to the lengths required to fit into the
carburettors and fuel pump. After the lines to the carbs were fixed in place with CA, the
distribution block was placed just in front of the right-hand side cylinder head, between
where the alternator and distributor would be placed.

 A Replicas and Miniatures tan pre-
drilled distributor, and Detail Master Red
Race Car Ignition wire were desirable. The
distributor base was painted with Alclad
ALC-107 Chrome for Plastic and cleared
with 2 Pack gloss clear. Detail Master
Wiring Looms were then used to route the
wires to the cylinder heads.

 The firing order (anti-clockwise on
the distributor) on Hemis is 1-8-4-3-6-
5-7-2. The ignition wire was fixed in the
distributor cap and the #1 ignition wire
was marked with masking tape.
