I have a quantum 50 engine Starts well when cold but have to remove plug wire brush it and replace (starts immediately)whenever I empty the grass box.Tried lots of different plugs,the problem has been there since new.Any suggestion please
Hard start when hot. Have you checked the spark when cols and hot, by taking spare spark plug and attaching it to the wire, and with it grounded, see if spark is good. If spark is weak when hot , replace the coil!
