Can ignition timing be set without power?

Multi meter method ;- set to continuity with "beep" to confirm the circuit, remove wire from points to coil and attach one lead to that, the other lead to engine cases (earthing) all the time the circuit is connected it will beep, meaning not firing, as soon as the beep stops when turning crankshaft that's the firing point of timing.

That's how it's done. If your multimeter does not feature 'a beep continuity' position, select Ohm and observe the digits go from 0 (closed) to I (open) or the dial move (analogue). Important is to disconnect the wire from the breakerpoints to the coil.

Thanks guys. Just what I needed, a clear set of instructions. I am looking forward to giving it a go.

Here's my high tech version

If the adjustment range on rotating the back plate won’t seem to accommodate the firing point, it’s often just a question of adjusting the points gap (to smaller I think) as this makes a sizeable difference to the firing point.
