[Healeys] Rough running

[Bob Spidell]

Yup. My BJ8 does the same, but I haven't driven the BN2 enough to say it 
does too (I presume it does/will).

You said 'would not restart,' as in it would crank, but not fire, or 
wouldn't crank? When a marginal starter gets heat-soaked they often 
won't crank the engine as fast which, of course, makes starting more 
difficult. Same with a heat-soaked, marginal fuel pump; it might not 
pump well enough to (at least partly) overcome cavitation in the fuel line.
