LBS.NOTE: Always verify timing of engine at room temperature only (68 0F/20° C).7. Verify and mark which flywheel timing line corresponds with the listed ignition timing from the chart at thebeginning of this unit. Refer to the method of using a dial indicator for verifying the timing marks, shown onpage 4.12.8. Connect an accurate tach and a good quality timing light to the engine.9. With the engine running at 3000 RPM, point the timing light at the timing hole.NOTE: Your sight line during the timing mark verification (dial indicator check) and the actual running timing lightcheck, must be the same.FLYWHEELROTATION!FLYWHEEL LINESPX< __ STATIONARY~ . POINTER10. Position your head so there is a straight line between your eye, the static timing pointers, and the crankshaftcenter line. Note the relative position between the flywheel mark and the stationary pOinter. If the flywheelmark is within the acceptable +/- variance, the timing is correct. If the mark is outside the variance, then thestator will have to be rotated either with crankshaft rotation to retard timing, or against rotation to advance it.NOTE: The recoil and recoil cup must be removed to loosen stator bolts and change the timing.11. Make sure all nuts and bolts are properly tightened after making adjustments.8/94 4.14
