Can any one help me , i have a early 90 with a 2.25 petrol engine.
i would like to know which timing marks to use, because in the manuel its says....
leaded fuel 90 octane set to T.D.C
leaded fuel 85 octane set to 3 degrees A.T.D.C
unlead petrol is 95 octane so do i retard the timing ? would this be ok?
I know how to set the timing but just dont know where to set it, and dont want to damage the engine.
many thanks in advance
