Hi all,
I've had my S2 P6B 3500 Auto (1972) for a few months now. The car had been laid up for some years, so i've been fixing various problems that have arisen since using it. The forum has been a great source of help, what a great bunch of expert contributors!
I have often had a problem with the engine stalling when coming to a stop, but it has always started again. However, now it will not start until the engine has cooled down a lot. It starts on first turn when cold and will idle OK (a bit rough though) and i can leave it to idle until it gets hot (when the thermostat opens), but then the revs start to drop and it cuts out.
Some symptoms are:
I'm suspecting the carbs, which are HS6. The engine serial number commences 451 with D suffix, and has HIF6 stamped on the tower, so not sure if this is a problem or not?
I'd appreciate any thoughts on what could be the cause before i go to my next step of reburb'ing the carbs.
thanks in anticipation,
Peter

Some symptoms are:
- fuel coming out of LH carb vent and breather pipe after it stalls. I think i've stopped this now by cleaning the suction chambers, pistons and replacing seats & needle valves in float chambers.
- all plugs are very sooty; and will get sooty again very quickly after being cleaned up
- I've fitted a colour tune to No.1 cylinder; it seems to get more yellow (richer mixture) as the engine runs and gets hotter.
