Hello Coilmotorworks. I am trying to do the drawings for a Rumely Model F to 1/8th scale that I want to build. One of the details I can't work out is how the clutch works. I can see that it is a friction clutch working on the inside of the belt pulley but how does the operating linkage work and how is the drive transmitted to the pinion which is on the other side of the belt pulley please?
