  • Last had an A10 in 1976, in 2011 it was time for my 2nd one. It was the project from HELL (but I learned a lot....)

If it’s not kicking back, I don’t see how ignition timing can make the engine harder to turn over.

I agree, and mine almost NEVER kicks back, and has auto advance (via BTH mag tho), and flat tops.

An A10 with the original domed inwards pistons (6.5:1?) I once kicked was SO easy to kick over compared to my bike I thought it must be low on comp but apparently it was on original bore and didn’t burn oil. It almost felt like it had no compression at all.

1949 C11 rigid, but why!!! (cos it was cheap)

1937 B21, project missing parts, mission impossible?

Its much easier kicking a bike over if the kickstarter is set a bit lower, say about 10 o,clock. Saves the knee joint strain too.

Sounds like your new rings have bedded in properly.
Yes, but six years ago I put new rings on these pistons and the bike started easier, as you can see in this video, taken soon after the rebuild: https://youtu.be/GL0wT8kriTA
Six years ago you where six years younger GB!

I do find that since the SA had a rebore with new pistons (flat tops, same as the ones that came out) and new rings there is noticeably more compression than before

I'd better learn to kick-start then!

Yes, I've been using the clutch to get get the kick starter half way down before I give it the boot.

Today I retimed the engine to 11/32" BTDC, as per the book I have not ridden it since then.
