remove the front cylinder inlet pushrod cover,
turn motor till inlet pushrod closes fully,
then turn it slowly by putting it in gear and rocking the rear wheel forward till the timing mark is central in the timing hole, at this point, with the magneto at FULL ADVANCE the points should JUST be about to open on the narrow cam lobe,
retard to start & you should be good,
IF you are bolting the mag solid at full advance, it will run & pull great but will be a bitch to start without being able to retard the timing,
you can bolt them so they can be turned by hand or cable to advance & retard when in use.
the 'finger on the plug hole' can work, but actually seeing the inlet valve close just before the timing marks visiable is better IMHO,

reverb,..... i'm personally not able to kick it as i'm disabled needing 2 new hips & knees but a buddy kicks it to life easy, havent got film of it being kicked to life sadly,
it isnt lose as such, mounted with a very smooth sweep to advance or retard, but in this clip near the end you see the strut pushing it to retard (when my buddy riding it remembered to retard it! ) without it flopping about.
