The perfectly adjusted carburetor delivers the proper fuel and air ratios at all speeds for the particular engine for which it was designed.
The carburetor should be maintained in its original condition and will continue to deliver the proper ratios.
To maintain accurate carbureting through passages and discharge holes, extreme care must be taken in cleaning.
REMOVAL
When removing carburetor from engine, take sufficient care to the following:
CAUTION
a. When disconnecting fuel lines, do not spill fuel from fuel pipe.
b. When removing carburetor, do not drop any nut or bolt into intake manifold.
c. Be careful not to bend or scratch any part.
CLEANING AND INSPECTION
Dirt, gum, water or carbon contamination in or on exterior moving parts of a carburetor often results in unsatisfactory performance. For this reason, efficient carbureting depends upon careful cleaning and inspection while servicing.
Before assembling and installing the carburetor, blow all passages and castings with compressed air and blow off all parts until dry.
CAUTION
Do not pass drills or wires through calibrated jets or passages as this may enlarge orifice and seriously affect carburetor calibration.
