Ive had to awake alot of cars from slumber in the past ,the marvel trick will make sure your rings are slick on the walls of the cylinder ,just let it sit for 3 days or more,purge it with the plugs out ,check all plugs while out, reinstall ,drain and check fuel condition ,clean carb on bench with carb spray ,reinstall with new carb to intake gasket, pre-draw gas from tank once the gastank has been visited with siphon,cleans lines of old fuel,,reinstall line, hot battery check, you want to turn the motor at the point when marvel soak is complete ,you can bump it with the starter but I like to see movement with a heavy wrench first just to see free movement .An Oil change would be also a good thing after you find it runs.
