Test data Ex:

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.
----------
L1=3mm L2=3.8mm

0000001901 V-FICD ADJUSTMENT

Adjustment of the V-FICD 1. Adjust the actuator rod to obtain S1. 2. Apply negative pressure P1 to the actuator and confirm the full stroke.
----------
S1=1+1mm P1=-53.3kPa(-400mmHg)

The existence of the fuel filter mounting bracket on the air inlet cover helps to determine the proper spacer to use. If the fuel filter bracket is mounted on the air inlet cover then the 135-5096 Spacer must be used. If the fuel filter bracket is not mounted on the air inlet cover then the
