TROUBLESHOOTING
Smoking Engine
Black smoke
Black smoke is an indicator of too much gas being burnt.
Blue or white smoke problem
Smoking engines indicates burning oil, probably caused by:
Over filling the crankcase with oil
Incorrect oil grades
Defective or obstructed crankcase breather
Crankcase air leak
Blown head gasket
Worn cylinder and/or rings
Turning/tilting the engine on its side
Surging Engine
When an engine surges or pants, it sounds as if the engine reaches full speed,
only to decelerate quickly. Engines rely on a precise volume of gasoline and air
to operate correctly..
Check the Air Filter
Clean foam filters with dish washer detergent and then apply a light coat of oil,
squeezing it into the foam. Paper filters must be replaced.
An air filter is a quick fix that should be your first remedy for a surging engine.
Problems in the Fuel System
Check and clean out the small vent hole in the gas tank cap for good ventilation.
Old gasoline, especially ethanol based, should be removed, the tank flushed
and replaced with fresh ethanol free fuel.
Check for rust in the tank, and consider lining the tank with Caswell Gas
Ta nk S ea le r.
Do not store your engine with ethanol based fuel in the tank. Run the engine
until out of gas and drain the tank. Spray tank and carburetor with a light coat of
WD40. Ethanol is your enemy. Avoid it whenever possible.
