First attempt to start on Tuesday. New fuel in, battery connected, kill switch off, chokes on, spin over and.... bang; the new drive pin in the output sprocket breaks up. Guess being a hardened steel pin it was too brittle, so all apart again (getting quick at this!) and a 1/4 inch stainless steel pin goes it and ready for second attempt.
Spin over, the rear motor coughs and ... bang, the long starter handle snaps where it meets the starter motor. It was only thin walled steel tube, so off to the metal supermarket again, and 600 mm of 25 mm diameter solid aluminium bar awaits machining and fitting for the next attempt..............
