I picked up this engine last year, and am rebuilding it as a spare for the Supervisors Inspection Car I jointly own.
The engine has a seized exhaust valve, which appears to be a typical problem with these motors. All of the engines I have come across, around the country, have had a similar problem.
This engine is set up for electric start, and has a dynamo that can (or perhaps should) throw somewhere between 10 and 20 amps.
As well as unsticking the valve, I will replace the main seals and gaskets. So far the motor appears to be in reasonable shape.
Typical of this size engine, this one is "splash" lubricated. The manual I have for the S12D and AELND indicates some were fitted with a proper oil pump.
This is an S12D, but not the one in this series of pages.
This engine is also suffering a sticky valve - needing an overhaul!
