0000001801 TIMER STROKE

Timer adjustment Assemble the timer's measuring device on the low pressure side and measure timer advance. Select one of the 6 timer springs. It is necessary to install at least 1 shim (0.6 mm) on either side. Maximum is L1 mm on piston side and L2 mm on cover side. Do not exceed. Use pipe corresponding to 146606-3920.
