340 Chugging instead of Reving

I once chased that idea round and round and no matter which tooth I set it to, the result was exactly what @Bewy says. And might I add; I total and complete waste of my time. Well not quite a waste; I did learn something. And I was very young so had lots of time ..... That was about 47 years ago, lol.
Ok so, don't go wasting your time, lol.
