My Speedy Tiger will often times feel like it's going to take off when i start it up... once backwards even, explain that, haha. I find that when i stop it (using the finger over the exhaust hole to do so) and reignite it, it's back to normal. Not sure how healthy that is but it seems to work more often than not. Hope it works for you as well.

Ryan, i was being facetious with the "it's easy." comment. No offense i hope.
