True enough. Both books and even better still, find on-line forums for more real world 70 years on solutions.

Far better, in my experience, is the little Pitmans manuals for most makes, in this case written by the AMC service manager FW Neill.
Usually these books are on Ebay for a tenner at most.

Or is it timed on the compression stroke?

The rear plunger section is likely from an A series or B series BSA, but as for the rest?

Grandma's eggs here, but you should wind the engine backwards a lot further, then winD forward until the timing point is reached. otherwise the lash in the gears will throw your timing out.
I usually start my bikes on just a little retard (rather than half) but all bikes are different and yours might need more retard.

No, you can't just centre pop the gears as you need to synchronise the position of the piston on the firing stroke with the position of the mag points.
Simple enough if you have a manual. FW Neill is a good one.

I've set the pressure plate run-out with a DTI, and you don't get a squarer lift than that.
Into Neutral before rolling to a stop is pretty much essential on many old bikes.

The OP could do the "quick and dirty" test to see if the problem doesn't lie with the mag or timing, namely set to TDC on comp stroke with lever fully retarded, then move lever incrementally advanced to find the best position and so prove the rest of the engine, carb etc.
If nowhere within that lever range produces a good running engine then you need to look elsewhere.
At full advance of the hand lever the timing will likely be too advanced so will need resetting at some point.

I've found the six-spring earlier clutch is even worse.
I've done all the things you have and now accept that it's as good as it's ever going to be. This is on an early Goldie, and spoils what is otherwise a great bike to ride.
Conversely the clutch on my plunger A7 (the earlier enclosed type) is as nice as that other much-maligned clutch, the Velocette, ie, very good.
That's a nicely engineered unit (unlike the cheap-arse BSA things) but the set-up instructions need to be followed to the letter, and many seem unable to do that.

Yep, always best to go "back to first principles" and check everything, especially when you see some of the dumbarse instant solutions on the Net.

Thing is, if it was shite in the float bowl it would cause problems whether hot or cold..

Brass would have been considerably dearer than other alloys when demand was high due to rearmament.
