rich #2 cylinder

[zeiss150]

Hey party people, ok problem # 968 :cross-eye I have an L24 with an E-88 head that has been totally re-built. I just adjusted the valves and I have the timeing down and i have the carbs synced and all my plugs look nice and brown except for #2! #2 is black and sooty. I checked for spark and its plenty strong the only thing that I can think of is that the intake valve is set wrong, but how can that be? 10 thousand's hot right!? that's what all the other intake valves are set at and the plugs are "golden brown". Could there be something wrong with the valve. allright people hook me up with your Z car wisdom.

Try swapping the plugs around, take the plug from 1 and 2 and swap them, drive it for a day, then check them again.

It could be just a weak spark plug, if the same plug fouls in number 1, it's the plug. If the plug you put in number 2 fouls, you'll know it's the cylinder itself.

How long since you adjusted the valves? And, have you re-adjusted the valves since you put the head on? If not, try re-adjusting the valves again. Drive it around a while and re-check the plugs. One thing to do while you have the valve cover off when you adjust the valves would be to check the wear pattern on the rockers, just to be sure the valves were set up with the proper lash pads when the head was worked on.

If you look in this thread, you'll get a good idea what to look for as far as as the wear pattern and contact on the rockers.
