McCulloch Manuals
Illustrated Parts Lists: (IPLs) are fairly simple. On the underside of McCulloch saws is a black and yellow tag; the upper number (“Power Mac 320” 600021H) is the model, below it a serial number (11-18555). These 2 numbers are combined to create an IPL number (“Power Mac 320” IPL number = 11-600021H). The IPL number can be used to find the correct IPL for every McCulloch parts supplier I’ve found. If the parts supplier only list part numbers the proper IPL is the source for the part number.
Operator’s Manuals: are much more difficult. I’ve dialed this number many times (Contact Us - All McCulloch Products 1 (800) 521-8559) and have yet to get a satisfactory response. Please try this! If enough of us try they will fix it! If unsuccessful with McCulloch try here:

Remove the spark plug and test for blue, snappy spark. If nothing, try a new plug set for 0.020" gap. If still nothing, remove the cover from the flywheel side to expose the ignition module. Remove the ignition switch wire from the module and try for spark again--if ok, check for a grounded ignition switch or the wire itself. If still nothing, replace the ignition module. Use a thin business card for a pole gap between the module and the flywheel magnets. Allow the module poles to contact the magnets, then tighten the screws. Rotate the flywheel to remove the card. If you got spark in the first test, then place some fuel mix in the plug hole and try to start. You should get several pops. If ok, then work on the fuel system. Check the fuel filter, air cleaner, and muffler for plugging. Check the fuel lines for decay or other damage. Make sure the carburetor fasteners are tight. If the machine is fairly old, you should check the condition of the lower chamber diaphragm in the carburetor--it may have become hard or cracked. Hope some of this helps!
