| -2- Contd. The motor kept the engine turning for 120 secs, the average speed was 32 to 35 r.p.m. The average time to start the engine was 2 to 3 secs. except for the first test the engine was not primed. The conditions of starting after the first start, were ideal because the engine when switched off would be charged ready to fire. The tests were ran off without any interval. The condition in service will be much more severe. There is no dount the electric starter will be an enormous boon, the fact that the battery when fully charged will turn the engine for 2 mins, continuously, should start any engine unless it is seriously out of order. There was no sparking at the commutation of the motor at any time. X.2814 We could not rig the Remy ugnition up conveniently, so a hand magneto wasused for the spark We have tried the Remy on the car and find we can start up by the starter quite easily also be pulling the engine over slowly.
