Old Lombardini engine - starting after sitting

[Toby in Buckinghamshire]

Evening all

 

I've recently bought a small 'garden' tractor for using at our small woodland for moving logs etc. It's been homeade by someone, based on a ride on mower chassis with a very old Lombardini diesel engine. 

 

The engine is running and seems pretty sound, although there is a moderate diesel 'weep' from the bottom of the engine. The tractor had been barn stored for a quite a few years.

 

I know very little about engines, even small ones like this but I was looking for some advice on what I should be doing to give the engine a thorough service. I'll change the diesel since it must be pretty old but beyond that I don't know what needs doing or how to do it. Any advice greatfully received.

 

Thanks
