ED Bee Mk 1 1.0 cubic centimeter displacement, manufactured in England in the 1950's. It was famous for it's ease of starting and reliability. See this little gem run on homemade fuel. I made this fuel using aa mixture of 60 % lamp fuel, 20% Castor ol and 20% Cold Engine Quick Start (Ether).  This was how she looked before she was fitte with a custom made compression screw and needle valve assembly.

  1. Hi there, I have done some clearing out at a house recently and found 3 model engines one of which is exactly the same as the one shown here (ED Bee MK1) I have no experience with these engines and would like to get this one running as nicely as yours. I think all the parts are still on it. How would I go about overhauling this little motor, I don’t want just take it apart in case I damage something. I also doubt whether it has runs for some tens of years. Any advice would be much appreciated. Thanks. Dieter

  2. Hi Contact! I never take these old engines apart unless something is broken. The running quality depends on a good tight fit of the piston in the cylinder which results in high compression, this compression can be lost by cleaning and removing carbon deposites. just inject some oil or fuel into the ports and gently turn the engine until it loosens up and turns over smoothly. Mix up some fuel, mount the engine securely, prime lightly at the exhaust port and begin flipping by hand smartly to get it to fire. These old engines keep well even when stored for many years.
