Notes
1)
Minimum recorded compression in any one cylinder should not be less than 70% of the highest recorded cylinder.
2)
Measured using an accurate shop tachometer at normal operating temperature. Idle RPM on EFI models is not adjustable.
3) Timing must be set using special procedures indicated in the appropriate service manual. Timing cannot be set using
conventional methods. Special tool(s) required.
4)
Always use dipstick to determine exact quantity of oil required. Do not fill above “FULL” mark.
5)
Do not over fill. Correct level is 3/4" below filler neck when coolant is warm.
