The mount looks okay, and I think I can see the lower nut peeking thru a gap.
To test the mount, open the hood, sit behind the wheel, start the engine, left foot firmly on the brake, emergency on, put into gear, and give it some gas, you will see the driver's side of the engine try to lift, if the motor lifts more than an inch or so, or jumps 3 or 4 inches, the mount or fasteners are faulty..
NOTE, remember where the ignition key is, to shut it off if it ever runs wild again.. and try not to put it in neutral before shutting the engine off,, or you could blow the engine when it over-revs.. ! ! !
