THROTTLE LINKAGE
ROCHESTER E2SE
No adjustment of the thro ttle cable can be made.
ROCHESTER E4ME AND E4MC
Due to the design of the throttle cable, no adjustments of the throttle linkage can
be made.
CHOKE UNLOADER (PRIMARY)
ROCHESTER E2SE
1. Connect a rubber band to the in termediate choke lever and open the
throttle to allow the choke valve to close.
2. Set up the angle gauge and set the gauge to specifications.
3. Using a vacuum source, retract the vacuum break plunger. Make sure
that the air valve rod does not interf ere with the retraction of the vacuum
