With the engine warm, turn the screw clockwise to increase the engine speed and anti-clockwise to decrease.The idling speed will vary, according to application. For details apply to the nearest Perkins Distributor o C.A.V. Dealer, alternatively Service Department, Perkins Engines Limited, Peterborough.Priming the Fuel System
The air must be vented from the fuel system whenever any part of the system between the fuel tank and injection pump has been disconnected for any reason, or when the system has been emptied of fuel.No attempt must be made to start the engine until the injection pump has been filled and primed as serious damage can be caused to the pump due to lack of lubrication.Later filter elements are self venting and do not have a vent plug fitted on the top of the filter cover.
