Note : During the running-1n period, the carburetters are set for a rather
rich mixture. It is necessary in the interest of fuel consumption to adjust
the needle position and the pilot air screw in the course of running in
accordance with the above table
.
c) When slowing down to a stop keep the engine at idling speed.
d) Check periodically all screws and nuts for slackness and after covering approx.
200 km. (120 miles) tighten the spoke nipples. We are especially pointing out the
necessity to tighten well the engine fixing screws (2 in the front and 2 in the rear
- the rear screws are accessible after removing the L. H. side box).
