I’ve just bought a Allen Motor Scythe (model T with the Villiers 25c 2-stroke engine) which I plan to restore. It has spent many years in a shed somewhere, not being used. The first questions that I have run into is, how do I change the oil in the transmission? In particular, how do I drain out all the old oil? It seems to have a filler plug, and a level plug, but strangely not a drain plug, which seems to imply that I have to turn the whole machine upside down to drain the oil out. There must surely be a better way? I would like to inspect the old oil for bits of metal, broken gear teeth etc. that may indicate other tasks that I need to do.
Other questions:
– can I use flushing oil in the transmission to clean it out, or will this do any harm?
– If I put a bit of oil into the cylinder through the spark plug hole, am I risking damaging anything by turning over the engine, and (once I’ve cleaned out the petrol tank and the carburettor) trying to start the engine?
Thank you – Rowan
