Misfire does not mean backfire, just the occasional 'bump and miss'. It starts just fine when cold or warm. See the video I posted.

The timing is dead-on the marks at 5deg BTDC.

Again, note that I'm responding with a bit of humility: Something I "know" is clearly not true or else I'd have figured this out by now.
