Subject: '81 Saab 99 GL - misfire under load

Hi! For a few months now my '81 99 (single carb, points ignition, 67000miles) has exhibited an occasional misfire at low revs under load, eg pulling away in 2nd or flooring the throttle in 4th at 30mph. Nothing major, just irritating. Any Ideas? I was thinking maybe lean mixture or dodgy coil or condensor as it only appears to do it when warmed up. It's had recent plugs (NGK BP6), leads, rotor and cap. Carb set to 3.5% CO at idle. Slight popping through the exhaust on over-run, but otherwise runs great. <Christian>
