The engine is equipped with two carburetors mounted at the upper side of the engine. The
carburetors are of the constant velocity type, installed to each manifold of the engine. For overhaul and
repair of the carburetors refer to the manufacturer´s maintenance and repair manual.

Note
Before discarding the removed filter element, cut the outer skin and check inside for
evidence of internal engine damage such as chips or particles from bearings. In new
or newly overhauled engines, some small particles or metallic shavings might be
found, these are generally of no consequence and should not be confused with
particles produced by impacting, abrasion, or pressure. Evidence of internal engine
damage found in the oil filter element justifies further examination to determine the
cause.
Note
When installing a new filter element, it is important that the gasket is clean,
lubricated and positioned properly, and that the correct amount of torque is applied
to the filter. If the filter is under-torqued, oil leakage will occur. If the filter is over-
torqued, the filter can possibly be deformed, again causing oil leakage. Lubricate
rubber gasket of new filter element with clean engine oil. A dry gasket can cause a
false torque value, again resulting in oil leakage.
