Cleaning And Adjusting Spark Plug; Checking Fuel System - Coleman F15BM Owner's Manual

You should periodically remove and inspect the spark plug because heat and deposits will cause the
spark plug to slowly break down and erode. If necessary, you should replace the spark plug with another of
the correct type.
Before fitting the spark plug, measure the electrode gap with a wire thickness gauge; adjust the gap to
specification if necessary.
When fitting the plug, always clean the gasket surface and use a new gasket. Wipe off any dirt from the
threads and screw in the spark plug to the correct torque.
1. Check the fuel lines for leaks, crack, or malfunction. If a problem is found, contact your
dealer and have this repaired immediately.
WARNING:
Check for fuel leakage regularly.
If any fuel leakage is found, the fuel system must be repaired by a qualified mechanic.
