I drain the petrol from the tanks and always start the show season with fresh fuel on the Fordson,D2 and the road roller. On my diesel powered machines I always keep the tanks topped up to prevent condensation build up.When I first had the 933G the fuel in it was stale and smelt like varnish instead of diesel.
