Excessive Oil Consumption/Exhaust Smoke; Engine Tends To Cut-Off At Full Throttle - PIAGGIO NRG Power DT Workshop Manual

NRG Power DT
Possible Cause
Starter inefficient
Battery flat
- Engine flooded.
Altered fuel characteristics
Defective spark plug or with incorrect electrode
Intake joint cracked or with a bad seal
Purifier-carburettor fitting damaged

Excessive oil consumption/Exhaust smoke

EXCESSIVE OIL CONSUMPTION/SMOKEY EXHAUST
Possible Cause
Excess of encrustations in the combustion cham-

Engine tends to cut-off at full throttle

Possible Cause
Maximum nozzle dirty - lean mixture
Dirty carburettor
Water in the carburettor
Air filter dirty
Defective floating valve
Tank breather hole obstructed
gap
ber
ENGINE STOP FULL THROTTLE
Operation
Check: electric wiring, circuit continuity, mechani-
cal sliding and power supply
Check the state of the battery. If it shows signs of
sulphation replace it and bring the new battery into
service charging it for eight hours at a current of
1/10 of the capacity of the battery itself
Start up keeping the throttle fully open alternating
approximately five seconds of turning it with five
seconds still. If however it does not start, remove
the spark plug, the engine over with the throttle
open being careful to keep the cap in contact with
the spark plug and the spark plug grounded but
away from its hole. Refit a dry spark plug and start
the vehicle.
Drain off the fuel no longer up to standard; then,
refill
Remove the encrustation, restore the plug gap or
replace being sure to use the types of spark plug
recommended at all times. Bear in mind that many
problems engines have, derive from the use of the
wrong spark plug
Replace the intake joint and check its tightness on
the crankcase and on the carburettor

compressed air
Empty the tank through the appropriate bleed nip-
