Default 1976 911 S runs smooth 'till 2200rpm then a bit rough through 3200.....

and worsens as it warms up through 210 degrees. Timing? Fuel?

Hi:

Its hard to tell much from your very brief description but offhand, I'd say that its likely fuel related.

I would see where your CO is set at with a 4-gas ot 5-gas tester.

I'd also suggest that you make absolutely certain that the ignition system is in perfect shape.
