Błock off inlef ports with rag to avoid dirt entry.

6.    Remove insulation panels from each side of the engine compartmenf leaving bulkhead panel in position and ensuring that the panel is lying flush with the bulkhead.

PREPARE CROSS-SHAFT ASSEMBLY. (Diagram 1. Photo 4).

7.    Remove ignition coil from fan housing. Remove the four appropriate hexagon headed set screws from fan housing and position the cross shaft support assembly. Between support assembly and fan housing position one O.D. x J" thick spacer at each of the four mounting points.

Using 4" long metric hex. set screws, plain and spring washers provided, secure assembly to housing but do not tighten. Loosen clamp screw on coil brackct and slide coil through bracket until it can be refitted on to fan housing using original mounting points. Tighten clamp, refit coil to housing and tighten support assembly.

Tighten mat down may disforf the cross-shaft support and make the cross-shaft stiff in action. In this case, slacken the six smali bolts holding the bearing blocks and allow blocks to take up a position giving free movement to the shaft. Tapping along the cross-shaft with a soft-faced hammer may help this process. Finally, tighten bolts.

Mount the rocking lever on its pivot bush with shims af either side and fit to the support bracket. Tighten the l£" x i" UNF bolt through the centre so that the pivot bush is firmly clamped between the sides of the support bracket. Now see how the shims need to be changed around to leave the rocking lever moving freely with a minimum of end-play and correctly aligned as in diagram 1. One or two tries may be necessary to get this perfect.

Connect up the nylon link from the top of the rocking lever to the second hole from the top of the cross-shaft centre lever. The whole mechanism should now work freely and smoothly.

PREPARE CARBURETTORS . (Diagram 2... Photos 5 & 6).

8.    (See also pamphlet G6604/SB211 supplied). The needles for the parficular Kit will be found packed with the inlet manifold adaptors. Remove the top cover from the carburettor by taking out four screws and lifting. Lift out the air-valve, handłing the rubber diaphragm very carefully. Insert the parallel end of the needle into the hole in the underside of the air-valve so that the shoulder on the needle is flush with the valve. Tighten the locking screw. Replace air-valve, diaphragm and top cover. Check that the air-valve fal Is with a click. If the air-valve does not fali freely, check that the diaphragm is correctly assembled without "kinks" and check the jet-centreing as described in the carburettor pamphlet.
