I'm fixing up a McCulloch pm700 and it's missing the oil cap. Also the fuel cap is cracked. Do other Macs share the same caps or does it have to come from a 10 series saw? I know the oil cap from my 1-52 doesn't fit.
Only 10 Series fuel caps will work, not the large frame saws, 600 Series, or any other McCulloch models will fit. I seem to remember that there were some Homelite fuel caps (XL??) that would interchange.
The oil cap from the larger saws will fit, but they are not vented and may not work properly through the whole tank of fuel. Some early 10 Series used the same caps as the large frame saws but they had a hole in the oil tank with a cotter pin stuck in it to act as a vent.
