Can you tell what’s going on here? Never a Sunbeam’s strongest point, a total of 4 missing teeth from this CT layshaft were located in the bottom of the gearbox housing. So that’s the 1930 M90 off the road until we can find a replacement set of cogs. It’s hard to tell what has gone wrong with this remanufactured set but a backfire whilst bump-starting the bike seems to have been the final straw for this particular old donkey.
