Hi there...I'm new to this forum and did not search the entire forum just yet. My Honda mower has been working fine...until today. I tried to pull start it and nothing...until now, it would start...reliably...with a single pull. Haven't checked much just yet but fuel is fine...recently topped up but was good fuel. Anything simple I may be missing? Did not check yet to see if the plug wire was seated properly...I guess that's really the first place to start. If you have a sequence of things I should check first, I'd appreciate that. Any particular web sites that are good to help here would also be welcomed. Thank you.
