Check fuel and oil line connections and repair any leaks. Make sure
that the cowling and baffling are in good condition and securely
mounted. Any damaged or missing part of the cooling system must be

If spark plug fouling has been apparent, rotate the lower plugs to the
upper position.
Examine the spark plug cable leads and the spark plug ceramics for
corrosion and deposits. This condition is evidence of either leaking
spark plugs or improper cleaning of the spark plug walls or connector
ends. Where this condition is found, clean with alcohol or MEK. All
parts should be clean and dry before reassembly.
Check the ignition harness for security of the mounting clamps and
make sure all connections are tight and properly torqued at the spark
plug and magneto terminals.
