Exhaust Line Installation
The exhaust line can contain too much water for length excess or negative gradient course that
returns back into the engine when the set is shut off.
The first water lock muffler is designed for avoiding that risk, but if fitted not enough lower
than the engine manifold either reversing the entrance with the outlet, or of too reduced capacity for
the return water volume that has to contain, can be unable avoiding the problem.
Particular care must be taken in designing the exhaust pipe course, preferring the alternatives
that keep self-draining towards outside as more pipe stroke as possible.
In any case, to be sure of a correct and safety installation, especially during the first
employment season, check often the lubrication oil integrity watching the engine steak level: a
transparent yellow oil if new or a black color if old, mean no water entrance, but an emulsion similar to
milk white/yellow not transparent or worst an increased level into the sump mean water flooding.
Another water presence signal becomes from starting difficulties as due to some roost on the
exhaust valve, the compression does not reach the proper burning value. Spraying some lubricating oil
into the cylinder while insisting with the starter, very often the engine can be started. Better if the
operation is made acting on the decompression device, for allowing some free engine revolution for
better distributing the oil and adding the flywheel cinetic energy. When started the valve self cleans, but
in some cases, of too long time water presence, also the piston rings are locked from roost, so the
engine must be opened for repairing.
In some cases the engine does not start for external reasons like lack of fuel, air bubbles, too
flat battery. While insisting, the water pump deliver a certain quantity of water that is not pushed out by
the engine exhaust pressure, remaining trapped into the exhaust pipe even if correctly fitted. If that
happens, drain the exhaust pipe when giving up the unsuccessful starting operation.
