Timing is at factory spec but I agree it could be (probably is) a lean
condition. I have an 84 SVO with the smaller 28 lb/hour injectors. I tried
putting the 35 lb/hour injectors on but ran into problems with it bogging
at sharp throttle transitions and a fair amount of black smoke at WOT. I
was afraid of contaminating the oil with too much gas so I put the smaller
injectors back in. Another possibility could be carbon deposits in the
combustion chamber. I figure the water/methanol mix will help if its a lean
condition as well as help clean out the combustion chamber if the problem
Over the winter I will be building a replacement ECU so I will be able to
use larger injectors with impunity.
