[Healeys] Rough Idle, was Valve gap

[Bob Johnson]

So...

if this:

"A clear sign if You set the gap too tight is that after some minutes of road
speed, You get rough idle (or no idle at all!) with some cylinders out.
After cooling a bit down, things go back to norm."

is true then I might surmise that once again a description of the way
my car runs has been made. Would this be the prime suspect in the way
my car idles when hot, or are there more probable suspects?
