I can't say just yet whether it pays to send your engine in for warranty repair, as I have yet to run mine through the break in period once more, I'll be doing that this evening.

I did, send mine in and all major internal parts were replaced, all except anything that had to do with the fueling system. I sent an email to HS in reference to this asking what's to keep it from leaning again? I have yet to receive a reply. :angry:

I'm going to put it back on my GP Showstring and if the same thing continues, I'm not going to give up, I'll just keep sending it in until I get either a new engine (one of those that claims to be working) or the darn thing fixed right. :angry:

Idea: :idea:
Why don't we all just flood OS, with our engines, perhaps they'll get the hint. pirate:
