turned it over 6 times by hand before starting.
it ran for about 5 seconds. and stalled.. no untoward sounds/smells.
It was on a hill with under empty fuel. so put 10Litres in, still no deal.
now checked plugs for fouling, coil packs, cas, all fine.
leads me to think im still not getting fuel.
Cas is bolted to the cover (clear cover)
