8. CARBURETOR<br />
8-1 OPERATION and CONSTRUCTION (See figs. 49 and 50.)<br />
8- 1 - 1 FLOAT SYSTEM<br />
The float chamber is located just below the carburetor body and, with a float and a needle valve, maintains a<br />
constant fuel level during engine operation.<br />
The fueI flows from the fuel tank into the float chamber through needle valve. When the fuel rises to a specific<br />
level, the float rises; and when its buoyancy and fuel pressure are balanced, the needle valve closes to shut<br />
off the fuel, thereby keeping the fuel at the reference level.<br />
