CHOKES
Automatic chokes may occasionally require
adjust-
ment to provide the best fuel-to-air mixture for the
existing temperatureconditions. Several adjustments
may be necessary
to
arrive at the correct setting. Let
the engine cool to ambient air temperature between
each adjustment.
If theenginestarts, runsforafew minutes, then stops,
the choke mixture may be
too
lean.
If the engine
starts, but runs
rough
and is sluggish once
it
has
warmed up, the choke mixture may be
too
rich.
