victa mower (af 055a-6) (crafstman ?)
I was operating it on low throttle instead of on full throttle ( was advised that this will give more torque) and i probably worked it too hard on some tough grass, the mower suddenly reved fast and stopped.
spark is ok (spark pulg 2 days old but with a lot of soot), removed spark plug and squirted fuel in and replaced sprk plug and still unable to start, removed fuel tube to carby and steady flow of fuel.
tried a week later. ( in case flooded)
still no go.
Had the mower for 6 years and no problems and use to operate on full throtle until recently.
