THE ENGINE CRANKCASE BREATHER
operator position several times to see that it is
free to move (as shown in Photo 7/54).
Notice, at this time, that the governor spring
completely relaxes its tension when the throttle
closes completely. Also, watch the action of the
governor spring when you open the throttle on
the handlebar. As you begin to go faster than
idle speed, the tension on the spring will in-
crease and therefore open the throttle shutter
on the carburetor.
Check the action on the carburetor's choke.
Moving the spring in toward the engine should
close the choke completely. When you let go, it
should spring back by itself. Make sure that the
throttle wire is free to move the full length of the
throttle cable. Apply some oil over the cable's
entire length to make sure that it remains free.
If your engine constantly needs replacement
of oil, or if oil constantly drips from your sponge
air cleaner after the engine stops, one source
of the trouble could be the crankcase breather.
First, make sure that your engine oil level has
not been overfilled. On new 6 H.P. engines,
make sure tl1at you fill the engine oil only up
to the full mark of the dipstick (see Photo 7/55)
when the tiller is in its normal sloping position
at the travel setting (that is, with the depth re-
gulator up to the top notch and the tines just a
few inches off the ground) for dipsticks marked
650r55.
If instead of having the depth regulator pro-
perly set, you have leveled out the engine base
and filled the oil up to the full mark with a new
engine, you have overfilled it with oil. This oil
will be drawn up through the breather into the
air cleaner where it will drip out. However, eith-
er a faulty functioning reed valve in the breath-
er, or dirt in the breather could cause the same
conditions.
