A commonly reported issue on generators using the Deutz F2L 912 / F2L 912 W is: Engine runs unsteadily and power output is low. Cause: Inadequate fuel supply, Valve clearance out of adjustment, valve spring broken, Nozzle needles stick, Level of motor oil too high, Level of oil in oil bath air cleaner too high, Inefficient compression due to seized or broken compression rings, or incorrect valve clearances, Cooling fins on cylinders and cylinder heads very dirty, Injectors defective, Injection pump delivery out of adjustment, Blocked blower air intake, Cooling blower V-belt broken, Leaks in lubrication system, Generator speed too low, Generator not charging battery because either the generator or regulator/cut-out is defective. Fix: Replace fuel filter, air-vent system, clean lift pump strainer, tighten unions, Readjust valve clearances. Have valve spring renewed, Have them checked by a mechanic, Drain off to upper mark on dipstick, Pour off all to reduce level to the mark, Have compression rings and piston checked by a mechanic, Readjust valve clearances, Clean coating fins, vertical ones on cylinder head in particular, Have them checked by a mechanic, Have it readjusted by a mechanic, Clear air intake, Replace V-belt, Stop engine immediately, Check unions on lubricating pump, oil pipe, oil filter and oil pressure gauge for tightness and tighten screws. Otherwise call in a mechanic, Check V-belt tension, Have it checked by a mechanic.
