Finally got Puch running sweetly. Out of the blue today....started her up and pedals are rotating (stop and start) with engine running which is a bit un-nerving as that's where you rest your feet. I stopped and re-started.....running normally again.
Bike has only done 900 miles from new so I can't see anything being worn. It was rumoured this bike may have been used for the UK Haynes manual....I would have thought they would have re-assembled carefully. Any ideas appreciated. Don't really want pedals spinning whilst riding ! Have a good day (27 degrees in UK).
