Layshaft is the correct way around. The problem is the G6 gear in that it has 19 teeth, noticeably bigger than the usual G6 that has 18 teeth. Being larger in diameter it binds heavily against G7, hence the notchiness.

The cam plate is operated bij the gear change mechanisme. there you shift the gears from 0 till 4 up en down.
Indeed it does.
so I guess you think there should be a G7 with 28 teeth but the chart MO12 shows G6 with 18 teeth on all ranges of gears (including the double backlash G6/2) except Close ratio with 19 with a G6/1 (which I suspect is what you have) but ALL show G7 with 29 I think that cannot be correct as has been said I dont think the close ratio was ever on general release so you have a one off thats looking for a partner, perhaps someone some where has a G7 with 28 teeth wondering why he has so much slop....
Perhaps you should get out the Plasticine and a magnifying glass- we Colonials like to keep things simple!
OM12 shows G6/1 with 19 teeth but G7 gear still has 29 teeth, so the G6/1 must have been cut on the same blank as the G6 gear. As far as it is possible to know G6/1 was never produced.
Perhaps you have a home produced gear, or a factory experimental item. John.
