• the fuel filter is not clogged
• the tank vent is not blocked or leaking
• the vibration damping springs and stops are not

Before replacing the fuel hose, measure the length
of hose between the crankcase and carburettor
and between the tank and crankcase. The correct
hose length between the tank and crankcase is 43
mm (1.69 inches). The correct hose length be-
tween the crankcase and carburettor is 53 mm
(2.09 inches).
