Gasoline Votalitiy; Stroke Gasoline / Oil Pre Mix; Fuel Delivery System (Carbureted); Carbureted System Overview - Polaris 340 CLASSIC 2006 Manual

Polaris recommends the use of Polaris lubricants and greases,
which have been specially formulated for the top performance
and best protection of our machines. In some applications,
such as the engine, warranty coverage may become void if
other brands are substituted.
Grease should be cleaned from parts and fresh grease applied
before reassembly of components. Deteriorating grease loses
lubricity and may contain abrasive foreign matter.
Whenever removing or reinstalling batteries, care should be
taken to avoid the possibility of explosion resulting in serious
burns. Always disconnect the negative (black) cable first and
reconnect it last. Battery electrolyte contains sulfuric acid and
is poisonous! Serious burns can result from contact with the
skin, eyes or clothing. ANTIDOTE: External - Flush with
water. Internal - Drink large quantities or water or milk.
Follow with milk of magnesia, beaten egg, or vegetable oil.
The carbureted fuel system contains many components which
directly affect fuel mixture and drive ability. When performing
diagnosis or carburetor maintenance, the entire fuel delivery
system should be inspected. The illustration above shows parts
of the system requiring periodic maintenance to ensure there is
no fuel or air leaks present.
Fuel filters should be replaced at least once per season. More
often if any contamination is suspected.
Fuel lines should be replaced every other season. More often if
they become brittle or swollen. Fittings should be inspected
for cracks or leaks. Do not use pliers or other tools that may
damage fuel lines when installing or removing fuel lines.
Call physician immediately. Eyes - Flush with water for 15
minutes and get prompt medical attention.

FUEL DELIVERY SYSTEM
(Carbureted)

CARBURETED SYSTEM OVERVIEW

Test run and check the fuel system for leaks any time parts are
replaced. Verify that all lines are routed correctly and away
from any moving parts.
NOTE: Some models use fuel filters that are located
inside the fuel tank. To inspect/replace filter, remove
fuel cap and use a long clean wire, bend one end in a
hook shape. Pull the fuel line that is in the tank up
through the filler hole. Inspect filter on end of fuel
pick up line. Replace if worn or clogged.
Red fuel line is the exterior line for outside the tank. The violet
line is the interior line for inside the fuel tank. They cannot be
interchanged! The violet line used inside the tank will fade and
turn clear after a relatively short time. This does not affect the
function or durability of the line.
