I checked the compression on my 65 Electra today... The lowest cylinder read 158 and the highest 165 PSI... I have checked my shopmanual but i cant find the correct value there, does anyone know how many psi it should be??? One more thing, the car is very fuelconsuming, i have checked the ignition,carburator, i also noticed that the switch for the stator switch did not work so i have replaced it, i have not checked if the fuelconsumption have improved since i changed it... All the sparkplugs had black soot on them so i adjusted the mixture screws on the carb and now they are white as they should be, except one which still is full of black soot, as the compression read the same on all cylinders i do not suspect any problem with the valves or rings...Does someone have a suggestion what it can be??? I also noticed vibrations when i reach about 40 mph and over, i have balanced the tires and that helped a little but not enough. The vibrations come about every second, its like whom---whom---whom, i dont know where to start looking, its very annoing... <img src="http://www.aaca.org/ubbthreads/images/graemlins/confused.gif" alt="" /> Thanks Jannelu
