Has anyone any ideas on how it may be possible to modify an existing gear set to be adjustable on the engine? This would mean separating the hub from the tooth row (inner and outer circles) to allow the gear mesh to remain in place while rotating either the crank or cam (probably the cam since it's larger).
I've sen cam drives for other engines which had plate over-laying the interface (separation line) which bolted to both parts, and the position was fixed with a dowel. This could be inserted in several positions, all of which were smaller increments than a single gear tooth (13.33°) to both correct errors and allow fine tuning with the cam in place.
I don't think there's enough market volume to develop it as a commercial product, but there might be enough interest to make 10 sets?
