  • Page 71: Carburetor Tuning

    660GC SERVICE MANUAL 22. CARBURETOR TUNING This section covers carburetor tuning. Included in this section are basic settings, idle speed adjustment, and complete adjustment. The carburetor on a new saw is set at the factory for optimal performance and compliance to EPA Phase II emmissions standards. However, minor adjustments may be required in certain conditions, such as high elevation. A replacement carburetor is not set correctly from the factory. Use the tuning instructions in this manual to adjust carburetor to factory-recommended settings. (DO NOT adjust the carburetor for maximum rpm. Adjusting the carburetor for maximum rpm will cause engine damage). Always set the carburetor jets to factory settings when replacement or complete rebuild becomes necessary. NOTES: • These saws are equipped with an electronic speed limiter, as part of the ignition system. This will prevent the saw from going above 12,500 rpm. Attempting to set the carburetor mixture to increase the speed or power beyond this limit may seriously damage the engine. • Always check the air filter, pre filter, fuel filter, and spark plug before making carburetor tunings and clean or replace if necessary © 2011 ICS | Blount, Inc.

    660GC SERVICE MANUAL 25. FUEL SYSTEM LEAKS This section covers testing the fuel system for leaks. Engine starvation can result from a leak or malfunction of any of the main components of the fuel system. The five main components are the fuel tank, fuel tank breather, fuel filter, delivery tubes, and carburetor. 25.1 Remove and inspect the fuel filter. A Replace the fuel filter if there is any foreign material in the felt or the internal screen. 25.2 Test the main fuel pick-up tube for leaks. A Connect tube to the pressure gauge and to the fuel line. B Pressurize the tube to 7psi (0.5 bar).

G If the main fuel pick-up tube does maintain pressure, then the leak has been isolated to the carburetor. Refer to the Walbro Diaphragm Carburetor Service Manual. 25.3 The fuel tank breather stabilizes the pressure in the fuel tank preventing both excessive pressure, which could flood the engine, and negative pressure, which could starve the engine of fuel. 25.4 Fuel tank breather is located inside the air filter compartment. 25.5 Testing the fuel tank breather. A Attach the pressure gauge and bulb to the fuel tank breather. Pressurize the tube to 7psi (0.5 bar). The pressure should reduce to nearly 0 psi (0 bar) over about 3 seconds.
