I took off the cover and found this. What had happened was one of the set screws fixing the inner chaincase to the crank case had worked loose and had pushed the triplex chain over one row onto the clutch housing. Both chains were bar tight. I slackened off rear chain and moved the gear box right forward, I could then dismantle the Alton set up and pull the engine sprocket and the clutch hub. You can see by the damage to the inner case how far forward the clutch had moved, the force must have pulled the gearbox forward on the drive side, hence the tight rear chain. Amazingly nothing is obviously bent or broken. My question is should I put all back together and press on or what? Has this chain 'jumping' event happened to anyone else? The Alton starter has no bearing on this apart from the set screw, my fault for forgetting the Loctite.
Cheers
