Question:
My new 543RS -only used for around 15 hours- is low on power and cutting out. The manual says to check the spark plug but not where to find it. Can someone please direct me?
Answer
See circled item in pic. The plug is located underneath the spark plug rubber boot. Note: The Spark Plug NGK CMR7H do seem to fail more than most plugs causing miss fires at full throttle. Expensive little plug. Also your power loss could that the carburetor is out of tune too.
