Default RE: Smallest CM-6 spark plug boot

There's some new chainsaws just out from Husqvarna and the have strato charged engines and also NGK CMR6H spark plugs as well as computerized mixture control on the Zama carbs. These are some of the first big saws I've seen that didn't have NGK BPMR7A plugs. 555 and 562

Notice the resistor type CM6 plugs!
