CHOKE BREAKER OPENING
NISOlWl
(1) After inspection of the choke breaker system, disconnect the
vacuum hose (yellow stripe) from the choke breaker and make
the following check.
(2) With the engine idling, close the choke valve lightly with a
finger until the choke valve stops. Then, measure the choke
valve to choke bore clearance.
Standard value : 2.3-2.5 mm (.091-.098 in.)
(3) If the clearance is not as specified, stop the engine, remove
the bimetal assembly and adjust the rod end opening for stan-
dard clearance.
NOTE
For removal of the bimetal assembly, refer to DISASSEM-
BLY AND REASSEMBLY (P.14-35).
-
When removing the bimetal assembly, put a mark on the elec-
tric choke body.
NOTE
(4) Reconnect the removed yellow stripe vacuum hose and mea-
sure the choke valve to choke bore clearance as in step (2).
Standard value : 3.0-3.2 mm (.ll&.I26 in.)
(5) If the clearance is out of specification, adjust by the adjusting
screw.
NOTE
| Adjusting screw turn- ing direction | Valve clearance | Expected result |
|---|---|---|
| Clockwise | Small | Better startability but plug more likely to get sooty |
| Counter clockwise | Large | Poor startability and stall more likely |
