Some information you might find useful before considering purchasing this item:
Not sure if the RPM (2250 RPM) indicated on the tag is the engine RPM or the output shaft RPM. The output shaft turns at TWICE the engine RPM. Engine governor is adjustable.
The engine will run at the stated RPM, the output shaft on the camshaft end runs at 1/2 engine speed.
Whilst the engine govenor is adjustable, it can only be used to make a +/- 5% change in engine speed, beyond this you will need to start thinking about changing govenor weights, and springs (all of which are internal).
This engine is anti-clockwise rotation (notice the unusual flywheel fanshroud and the letter Z in the serial number), if you have ever started an anticlockwise rotation engine, it feels alien compared to a clockwise rotation engine. The starting handles are interchangable, providing you turn the pawl though 180 degrees.
It is a Lister SL engine and not LD as the seller has described. This is an uprated version of the LD and has a 3.3/16" bore compared to the LD 3" bore. Hence there are many internal detail differences, and piston components are starting to get tricky to source if you want genuine OEM parts.
