Hi Aero Nut,
                   The EH prefix engines were fitted to the 1927/28 Douglas model SB27 motorcycle. These engines are 600cc. Douglas also  produced a version for use in industrial trucks. I have looked in books by Jeff Clew and Brian Thorby but cant find any reference to these units powering any aircraft - but this doesn't mean they weren't used - there are a couple of references to earlier 4HP (600cc) engines being fitted in aircraft.
   Hope this is of some help,
          Regards,
                       Eddie.

Hi Eddie

thank you so much for the info

this engine has both a mag  and a dizzy ......
and a very strange imlet manifold .....

I am thinking of   using  it in a cycle car  project ... just need to find dizzy cap and mag cover and a few bits  ..

are these engines total loss oil systems ????? 

thanks again

Bruce,

It started as a standard motorcycle engine, to which a distributor and a few other piercings have been added to the timing cover. The very top of the timing cover has been cut off; it had a false front effect that covered a little of the arch of the inlet manifold. The inlet manifold is homemade and probably dates to when it was being converted for Aero use, though it sort of appears that the conversion was never completed.

The engine has a total loss oiling system. Some of the extra holes in the timing cover look as if to tap into the oil galleries on the inside face of the timing cover.
