As said before check your reeds, I had the same problem before. My reeds were not properly seated, they slid down just a little and my engine would die when I hit the throttle. Took them out, reinstalled the whole reed assembly carefully and voila my problem was fixed. If that doesn't help try removing your TORS if you havnt already. There are a couple great threads on TORS delete/removal on here under DIY. Hope one of those solves your problem !
Don't you just love it when ppl post a question or ask for help, get a bunch of great advice and then don't post anything back. No status update, no THANKYOU, no nothin !
