I will give up a secret from the Master Motorcycle mechanic that trained me. You can force almost any gas or diesel engine to start with WD 40. It's very flamable. It won't dry the walls or piston up like starting fluid. It will also remove chewing gum. It will take bird poo off of paint also Used to use it on the chrome bumper on my Freighliner to keep bugs and road tar from sticking to them.
