1978 mgb 4cylinder has not been run for over 10 years. What must I do to get it running?

Pull the spark plugs and add a small quantity of light engine oil mixed with diesel into each bore and let sit for a few hrs, attempt to turn engine by hand (DO NOT CRANK ON KEY) if tight, work back and forth gently until it moves freely, this will help un stick rings, cranking on the key may break any stuck rings. When turning freely crank on key to expel any fluid in bores, place a rag over plugs as it will expel with force, change oil and filter clean carbies and blow out fuel lines replace fuel filter, flush tank, and ensure fresh fuel is pumped up to carbies, remove thermostat and check for muck flush radiator and block (heater if fitted) checkpoints fit new and plugs, then you can start engine. You may find leaky water pump and engine seals after a few runs as the seals do dry out and shrinking from non use, this will be the same for brakes and drive line, so be prepared foe a few problems along the way.
