Just to second what Mike wrote, and could I also suggest heating the plugs over a gas hob before trying again.
Unfortunately, the coils are also a bit weak, and they do fail, the difficult bit is that it ran, then stopped, suggesting that they’re ok.
It actually needs very little choke once it’s running, and will quickly die if you leave it to idle on full choke (I checked with mine this afternoon). It’s best warmed up by sitting like a lemon holding the throttle open. On mine, from starting from cold ( first time since November, tho it started 2nd kick on 3/4 choke) it took over 5 minutes before I could let go of the throttle.
