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.
Main Jet and Pilot Jet
Pilot jet
no. 10
and main jet
no. 9
are replaceable.
Different jet sizes are available to suit temperature
and altitude conditions. Always inspect spark plug
tip condition when dealing with pilot jet and main
jet. Spark plug tip condition gives a good indication
of carburetor mixture setting.
CAUTION:
Adjustments vary with temperature
and altitude. Always observe spark plug condi-
tion for proper jetting.
NOTE:
To have access to pilot jet
no. 10
or main
jet
no. 9
, check valve housing must be removed.
