(Ref Fig. 5 on page G-5). Loosen the tensioning bolt (1/4
- 1/2 turn). Rotate the engine one full turn which will allow
the spring to apply tension to the belt. Tighten the idler
adjusting nut to 10 - 13 ft. lbs (14 - 18 Nm) torque. Spray
the rubber plug with a vinyl protective spray in order to
ease the installation of the plug.

section 'A'.
Compression tests are one of the most accurate meth­
ods of analyzing engine performance. To obtain maxi­
mum efficiency from the fuel explosion, the combustion
chamber must be sealed. Efficiency can be affected by
problems with rings, pistons, head gaskets and valves.
Most problems associated with these components can
be detected with a cylinder compression gauge. Incorrect
use of a compression gauge can result in unnecessary
work and expenditures (Ref Fig. 6 on page G-6).
Compression gauge E-Z-GO part number 72524-G01 is
recommended.
To properly perform an accurate compression test:
1. Remove belt to clutch.
2. Remove the air filter to eliminate the possibility of a
restricted air passage.
3. A well charged good battery should be used. Weak
batteries may not allow the correct cranking speed.
4. Starter belts that drag or slip will affect the compres­
sion reading.
5. Fully open the choke and accelerator baffle plate.
Should either of these baffle plates be partly closed,
the compression reading may be inaccurate and indi­
cate low.
6. The engine must be at normal operating temperature
in order for the components to expand.
