I heard that. I run the thing with the throttle lock set at about 3/4 and use the rest as a booster shot when needed.
Here is a link to what Stihl answered in their FAQ's. I can't seem to find it in the Husky info at the moment-
Q-"My instruction manual says not to run the product at full throttle for the first 2 to 3 tanks of fuel mix. Why is this?"
A- "This can cause internal engine damage. STIHL recommends that you do not run your engine at wide open throttle without a load. A blower is under a load at all times, a trimmer is under a load as long as the trimmer head is in place and the line is to the correct length, while a chain saw is under a load when the bar and chain are in a cut."
It's the first FAQ in this link-
