I've now managed to get the 1914 2 3/4 HP stationary engine running for the first time today and it can be seen on [https://youtu.be/ZPYq1QbO2vc]
We had a lot of difficulty in getting it fired up until we heavily flooded it when it went without any trouble at all.
The engine appears to be very similar to a 1912 model G (particularly LE 1848) including the inlet manifold and carburettor apart from the latter apart having rotary valves for the choke and throttle instead of being vertically operated by Bowden cables on the model G. The lower part of the crankcase has a longitudinal semicircular groove which appears to have been half of the clamp to a tubular part of the frame but, in this instance is, clamped to a casting which enables it to be used as a stationary engine.
I'd very much like to hear from any owners of similar engines to learn basic details such as valve clearances, grade of oil and recommended starting procedure.
