Sparey Twin

Sparey Twin 2cc 

by Ron Chernich
 

We Motor Boys often got up to some crazy ideas, and in the year 2000

Ron Chernich and myself decided that we would each make an engine

to celebrate what everyone called “the Millennium”. The little engine

known as the Sparey 0.8 [actually 0.64cc] had long been one of my

favourite flying engines, and since I fancied the challenge of a twin, then

a twin based upon two little Spareys, making just 1.28cc, was my choice.

Ron had already built a few little Spareys in 2000 but he had up-sized

his to 1cc. Consequently he fell in line with my plans to build a twin, but

his was to be 2 x 1cc based on his success with the single.

One last tip. Add a few drops of Sewing Machine Oil (or any other oil) to make everything lubricated
