Ouch.
Now I know why Tony insisted the fan blades on my new (six years ago) engine be welded.
At the time, I asked the engine builder how many revs the engine was safe to. He said about 6200. But, somehow, I've never had it over 5000.
Deep inside me (I think it may be somewhere between my shoulder blades), there's a rev limiter. The engine revs easily to 5000, and starts pulling really well over 4000, but it's MY rev limiter that kicks in around there.
It just doesn't sound right to me winding the thing up that high. It sounds like I'm tempting fate. Like something very well might let go.
None of my modern cars have done that. They sound the same at 5000 as at 3000, only a little louder. My old 2002 would hum along all day at 5000 (about 85 mph) and sounded, well, purposeful doing it.
This Briggs and Stratton is of another era, though, and - to me at least - sounds that way. I respect its age.
And just where are you going in such a hurry, anyway - marooned as you are on that tiny, little island? You're going to careen around some corner and fall into the ocean.
You'll shoot your eye out.
