Fuel System/Dynamic Timing DYNAMIC TIMING AT NO-LOAD NOTE: Dynamic timing at no-load can be checked only by using the stroboscopic lamp while the stroboscopic lamp can be used also to check dynamic timing at full-load. CD30194 -UN-07MAR95 1. As the value for dynamic timing at no-load is close to 0˚ and since the timing meter is less accurate for these values, an additional mark (D) with a 10˚ offset angle should be made counterclockwise from the TDC mark. The specifications for “No-load” in this group include this 10˚ angle. Value for “X” according to pulley diameter: A—Stationary pointer B—TDC mark C—Pulley Dia. 142 mm (5.59 in.) . . . . . . . . . . . . . . . . .

NOTE: If the pulley diameter is not listed in the above chart, use the following formula to calculate “X”: “X” = diameter x 0.087.

The display will show “Time-Trac”, then “Model TT1000”, then “R = 0”. NOTE: At this point, meter can be used as a -UN-07MAR95 tachometer. 3.
Start the engine and run for 10 minutes to reach the operating temperature. CD30202 CD,3274,G40,58 -19-04JAN99 40 53
