The Museum is currently closed to the public for building work and I am using part of the floor space as a general workshop the Avon engine along with a RR gnome 1300, Bristol Hercules and a few other industrial engines are on the to do list for restoration.

The starter mounting is on the front of the engine, Any ideas on how the starter clutch works.

The only other avon i have seen minus starter had a planetary gear set in the front, I will put up some pictures of the 28R starter arrangement when i get a chance.
