Starting Birmingham Scott after long rest

[Erik]

In my 1927 Flyer gearbox I use Millers SAE 40 monograde oil. This oil has only little additives and is designed for use in older engines. I use the same oil for lubrication of the engine (fed by a modern, throttle controled oilpump). I never drain the reservoirs/wells.

Just to be sure I use a 1:50 mix in the petrol. For that I use a normal, mineral two stroke oil.

My Scott does on this setting not really smoke.

Carl,

Just to clarify – I have a reduction gear on my machine so the Pilgrim is rotating at half the speed of a direct drive pump, hence 2 spits & a drop is equivalent to 4 spits & a drop on a direct drive pump. We therefore appear to be using the same settings, but I use modern synthetic oil as recommended by Glyn (and I do not do any really hard driving like Roger, who recommends R40, does)

Hi,Brian, The postwar manual for the engine,gearbox and lubrication is the same as a Birmingham Scott.The idea of the crankcase wells is to retain oil to lubricate the big ends on initial start up this is exactly the same as a two stroke with petroloil lube.Don’t drain the wells after a run. If you see a Scott with transparent oil pipes you will see the oil flowing into the engine in beads,it looks just like a chain it certainly is’nt just a smear on the walls of the pipe.If you want to get oil through the mains and into the big ends you can disconnect the oil pipes to the engine at the pump push on a length of rubber hose ,blow down it with your mouth, slowly rotate the engine until you feel the pressure release you now know that the hole in the gland is in line with the hole in the main bearing cup, pump oil in with an oil can and repeat on the other side.Take great care with the connections on the pump as the threads are easily stripped. If you have rotated the engine before you drained the wells there should be oil on the bearings I would put a drop of oil down each plug hole,fill the bowls on the pump open the adjusters half a turn and start the engine and not bother about the oil can bit. Colin 2 spits & a drop will be the same regardless of the RPM of the pump and not equivalent 4 spits & a drop at engine speed. Best wishes Ted.
