Cylinder Cancel Test
Used to determine which cylinder has a problem.
The cylinder that does not affect the speed or sound of
the engine is probably not doing its share of the work.
If the engine has a knock and the knock goes away, that is
the cylinder causing the knock.
If the knock doesn't go away then it could be a
mechanical problem. (ie. Piston hitting the head).
Crankcase Breather
Another component to look at is the Crankcase
Breather
Maintains pressure in the crankcase at less than
ambient pressure to assist in the control of oil
consumption.
Excessive engine blowby renders the breather
useless.
Old engines vent to the atmosphere.
New engines vent to the carburetor.
