ASSEMBLY
POP-OFF PRESSURE TEST
Proceed as follows:
– Install pump gauge tester on carburetor fuel in-
let nipple.
– Obstruct fuel return nipple with a finger.
– Pump tester until inlet release pressure is reached
(seen by a sudden pressure drop).
TYPICAL
1. Pump gauge tester
2. Install on inlet nipple
3. Obstruct outlet nipple
Refer to the following table for pop-off pressure
specifications:
NOTE:
Pressure test should be performed three
times to obtain a valid reading.
If pop-off pressure is not within specification,
check control lever adjustment. Replace spring as
necessary.
CAUTION:
Do not stretch or cut spring.
LEAK TEST
Needle valve must stand a pressure of 69 kPa
(10 PSI) for 30 seconds. Otherwise, hold carbure-
tor upside down, pour oil over needle valve and
apply pressure.
Check for bubbles. If they come from seat or
O-ring, bubbles will exit around seat. Retighten as
necessary.
If it still leaks remove needle and seat and replace
O-ring.
If bubbles come from needle, replace needle and
seat.
ADJUSTMENTS
Throttle Cable Adjustment
NOTE:
Do not activate throttle lever unnecessari-
ly. Carburetors are equipped with fuel accelerator
pump. This pump is injecting fuel into carburetors
each time throttle lever is depressed.
Throttle cable is equipped with a sensor which will
send a signal to the MPEM at 80% throttle open-
ing in order to control the spark advance.
THROTTLE CABLE ASSEMBLY
1. Sensor
2. Throttle lever section
