Est. 1950 Mall-Remington experimental/prototype chainsaw engine
Opposed piston design
2 crankshafts, 2 pistons & 1 cylinder
2 stroke, requires oil/gas mix
Both cylinders & middle head are one casting
Designed from 2 saws that Mall/Rem produced at the time. 1 cylinder is from a GL7 direct drive saw, and the other is shared from a GL7R gear or belt drive saw. This was required because the engines mirrored each other, making it simple to design because both intake & exhaust ports were on same side as each other.
This engine has a displacement of almost 13 cubic inch (210cc)
6.5 c.i. (105cc) multiplied by 2
Both the GL7 & GL7R saws were 6.46 cubic inch (105cc)
Bore 2.25 in (57mm)
Stroke 1.625 in (41mm)
Engine runs well, ignition coil was bad. I substituted with a 6v battery ignition & a Rowland RMC coil out of New Washington, Ohio
The engine was thoroughly inspected, serviced & identified by Larry @ House O Saws in Litchfield, Ohio. World known chainsaw collector of 7000+ chainsaws.
