Take the plugs out and give give them pistons a good soaking with Marvel it will help if they are stuck and if there not it will lube the pistons and the cly. walls so it will be easyer to turn her over,I always soak with marvel and change the oil and add 1 qt. marvel with the oil before I try and turn the engine by hand if all seems OK I'll crank it over with the starter but no plugs if it still seems OK try and start ,thats after new plugs, points,condenser are installed.
