I have cleaned the air filter and checked that there is oil, and clened the spark plug, but it still will not start. What is the replacement spark plug for this engine?
Replacement plug is a Champon RJ18 or equivelant. Check that the primer is actually pumping fuel (remove wir filter and look - it's obvoius. Use FRESH fuel - the stuff left over from last season will NOT work (at least, not with a cold engine).
