Question about 1994 Oldsmobile Cutlass Supreme
1969 ,points and distributor ,,,, then unleaded petrol 95 i would set it to 6º at idle ,now as this vehicle was designed to run on leaded fuel with a higher compression than that used on modern cars you could use a lead substitute and set timing to 10º on idle ,now iam not sure if this vehicle had stellite coated valve seats and valves and only a dealer might know ,now if it hasnt got stellite valves and seats then you must use the lead substitute or the valves will burn out ,but if the negine does have stellite valves and seats then it will run quite happily on the unleaded fuel with the timing retarded a bit ,i mean i bet its a 4 litre or something so a slight loss of power will not be noticeable ,but a 998cc morris minor its quite a difference
