yea you do not whant any petrol/gasoline is these Nitro modled engines. If it keeps flooding try replacing the glow plug cause a worn out glow plug won't ignite the fuel when weakend or damaged and it will cause the engine to continue flooding. If this doesn't help you may need to check your engine cause if an engine bering is worn out it will cause the crank to of center and make it hard for the starter or check the flywheel a bent flywheel would make it hard to pull the starter. try these I hope they help.
