12-1. Run-In And Wetstacking

1 Welding Generator
Run-in procedures for this engine
should not be required. Put unit into
regular service.
2 Engine Exhaust Pipe
Wetstacking is unburned fuel and
oil in the exhaust pipe and occurs if
the engine is run too long at light
load or idle rpm.
If exhaust pipe is coated with a wet,
black, tar-like substance, contact
factory service for procedures to
properly dry engine and seat piston
rings.
