Carburetor Adjustments - Westerbeke 5.0KW BCG-60Hz Operator's Manual

CARBURETOR ADJUSTMENTS
CARBURETOR
The carburetor is a single barrel, side-draft type with a
cleanable metal screen air intake filter/spark arrester.
The choke is operated by a 12 VDC solenoid. This choke
solenoid is activated when the ON switch is depressed and
stays activated so long as the ON switch is held depressed.
Once the ON switch is released the choke solenoid deactivates.
Air Screen/Flame Arrester
The air screen can easily
be
removed. Clean after the first 50
hours of operation, every 100 hours from then on. Clean the
air screen in a water soluble cleaner such as GUNK.
Drip
Tray
Do not allow fuel to build up in the drip tray. Use the allen / /
screw drain to remove
any
fuel build up.
