A .,. ...s.I....., ..,.. .~eedle seat, assemble new needle to float and install it in float bowl.<br />
Check float height with the gage from the rebuild kit. Gage works for several carburetors,<br />
so refer to the specification sheet to find the float-height you are checking. Rather than<br />
pushing down on the needle-end <strong>of</strong> the float to check height like thls, hold carburetor<br />
upside down so float is hanging.<br />
Before installing the bowl cover, install<br />
the choke vacuum-break diaphragm<br />
assembly if your carburetor is so equipped.<br />
A flat nylon seal goes under the cover to<br />
seal the diaphragm linkage. Don't forget<br />
it. Install the bowl cover with its gasket,<br />
four bolts and the center air-cleaner bolt.<br />
When installing the idle-mixture screws,<br />
run them in until they bottom lightly,<br />
then back them <strong>of</strong>f the same number <strong>of</strong><br />
turns you noted during the teardown.<br />
<strong>Your</strong> carburetor may not be set exactly<br />
right for idling, but the idle-mixture adjustment<br />
should be close to the correct<br />
setting.<br />
<strong>To</strong> complete the assembly, install all<br />
the hang-on parts, the choke, throttle<br />
solenoid or dashpot, choke vacuum can<br />
and a new filter. Hooking up the linkages<br />
to all these parts and getting everything<br />
adjusted can turn out to be the most challenging<br />
job <strong>of</strong> rebuilding your carburetor.<br />
Follow the kit instruction sheet closely.<br />
TESTING AND CALIBRATION<br />
After your engine is installed with its<br />
new or rebuilt carburetor and distributor,<br />
you'll want to make sure they will perform<br />
at their peaks-maximum mileage<br />
and power with a minimum amount <strong>of</strong><br />
pollutants. Distributor and carburetor<br />
tuning are major factors in determining<br />
an engine's performance, and to tune<br />
them to their full potential requires expensive<br />
and sophisticated tuning equip-<br />
.,. ment at the hands <strong>of</strong> a tuning specialist.<br />
This is the subject <strong>of</strong> the last chapter.<br />
Adjusting float height. Bend down tab from which needle hangs to lower the float. Bend it<br />
up to raise float. Install float and recheck its helght.<br />
Install choke-linkage dust shield and top gasket. There may be a couple <strong>of</strong> these gaskets<br />
in your kit. Find the correct one by matching it up with your old gasket. Dust shield prevents<br />
unfiltered air from being drawn Into the carburetor through the choke-linkage<br />
clearance hole.<br />
After carburetor top is in place, you can<br />
add all the external hardware. Don't forget<br />
to replace the identification tag. Finish up<br />
by installing throttle solenoid.
