Lister HA4 diesel - Purge oil system and then first start in 2½ years.

Awaiting the rewound alternator I prepared the Lister HA4 engine and see if it wants to start and run. Important when an engine has not been used for a long time is to purge or prime the oil through the bearings, before the engine is fired up. On a diesel best way is to keep the fuel supply cut off and run the engine on that starter till the oil pressure has built up.
