1924 ~ 27 Blackburne Single Cylinder Engines Hints, Tips and Parts List.

For a lot of small motorcycle manufacturers it was financially impractical to design and build their own engines, so larger companies like JAP, Sturmey Archer, Villiers and Blackburne provided them with the power units. Therefore this manual should be of a huge benefit to owners of such machines as Rex Acme, Cotton, Toronda, OEC, McEvoy and Chater Lea.
At 28 pages the manual has the usual staining indicating a well used handbook, and information contained within is for the 250, 350, 500 and 550 models, both side valve and OHV engines. There is a section on General Notes on Running and Adjustment which includes valve clearance and adjustment, ignition timing as well as an illustrated parts section.

Even though the cover states that the manual covers single cylinder engines there is also some illustrations of the parts for the water cooled V twin engine that was possibly fitted to the Morgan 3 wheeler.
