1980 Lister Petter AC1W
Lister Petter AC1W - Year of Manufacture 1980
This engine arrived with MPS for repair. It is a 1980 built Lister Petter AC1W. 6hp @ 3000rpm, Although alot smaller than the engines that are normally found in our workshop this Petter AC1W was sent to us due to repeated unreliability and its eventually reluctance to run at all. As you can see in the photo's the cause was quickly apparent with the removal of the rocker cover as the engine had broken a valve spring resulting in the valve dropping into the cylinder. The engine was repaired and re-assembled before returning to it's owner.
