David,
When it runs rough during that "short time restart", do you observe the
exhaust color running "rich"? I've seen conditions where the float level is
just
high enough and the float needles are just sticky enough to allow fuel to
get past the float needles after the motor is turned off and collect in the
intake manifold. This will only happen for a short time until the residual
fuel
pressure from the fuel pump is drawn down. So, after an hour of engine off,
the fuel evaporates but after a few minutes the fuel is there and rich enough
to load the engine and cause rough running.
If the engine isn't running rich during this "short time restart" then we
have to think of another cause. If the engine starts well you'd think that
there's enough fuel in the bowls so fuel percolation or low fuel levels in the
bowls don't seem to be the culprit. During the "short time restart" running
(when it's running rough) does pulling the choke out make it run any
differently?

I
can get it to clear, but intermittently returns to rough running.
