Why won't my Hayter Harrier 48 Autodrive VS ES IS engine start?

Your Hayter Lawn Mower engine might not start due to several reasons: the engine may be under load, so raise the height of cut; incorrect or contaminated fuel, so drain the tank and fill with the correct fuel; disconnected spark plug lead, so connect it; removed electric start button, so insert it; engine brake not released, so operate the engine brake lever; faulty spark plug, so clean and adjust the gap or replace it; or a wiring fault, so check the wiring.
