Ignition timing, 760 GLE
The ignition timing should be inspected at the 600 - 1,200 mile (1,000 - 2,000 km) inspection. All adjusting work should be done with the
proper equipment. The distributor is one of the most sensitive engine units. Careless handling can lead to decreased engine output, high fuel
consumption, and even serious damage to the engine.

Evaporative control system
The 760 is equipped with a gas evaporative control system, which prevents gasoline fumes from being released into the atmosphere.
The system is comprised of an expansion chamber in the fuel tank, a roll-over valve on the cross member in front of the fuel tank, and a
charcoal canister with built-in vacuum valve under the left-front wheel housing.
The components are interconnected by hoses which channel fuel vapor from the gas tank to the charcoal filter, where it is stored until the
engine is started and then drawn into the engine's fuel induction system.
Crankcase ventilation
The engine is provided with positive crankcase ventilation which prevents crankcase gases from being released into the atmosphere. Instead,
the crankcase gases are admitted to the intake manifold and cylinders.
PCV system, B28F
The orifice nipple in the intake manifold should be cleaned every 60,000 miles (96,000 km)
Check/replace rubber hoses at the same time.
