Is the string trimmer supposed to seem less powerful (slower, less kick, quieter) at full throttle in short grass and then rev up in taller grass and weeds?  Also, does anyone's string trimmer rev up and get more powerful when you bump the head?  The line is long enough, but bumping it always seems to make it run better for a while.  I called customer service and they said that shouldn't happen and that I should return it, but I love the trimmer and am reluctant to return it. 
It does seem to lose power intermittently, but more in short grass than tall grass even though the throttle is fully depressed.

The trimmer speed should stay more or less constant as you work. If you really load it down it may over-rev a little when you first remove the load, but it should not vary so much that it sounds like it’s doing it intentionally. It’s hard to say with 100% certainty without being able to hear it.

I believe what they meant by “return it” was to exchange it for a new one at the store. ;-)
