I broke in my new hyper .21 according to these instructions: [link=http://www.rcuniverse.com/forum/m_3443146/anchors_3443146/mpage_1/key_hyper/anchor/tm.htm#3443146]the one by foxy42[/link].

Well I got all through the break-in and was going to begin to tune it but the weather turned foul on me so I didn't get a chance for a couple of weeks. So today I try and go tune it. It fired right up on the 3rd or 4th pull, but then died. Same thing over and over. It wouldn't run for more than 3 secs. It sounded like the engine was getting bogged down or flooded right before it died. So I tried turning in the needle valve 1/4 turn thinking it was getting too much fuel. Same thing. I finally got it to run steady, but only if the carb was 1/2 open. If I let it go to idle it would just die. If I went to WOT it would just die. Basically it will only run at 1/2 throttle. Any more and any less and it dies. At the end of me breaking it in a few weeks ago, it would idle steadily and ran awesome. Now, I'barely runs at all. I'm completely stumped.

I'm using Blue Thunder 20% and a McCoy #7 plug. Fuel is brand new as is plug.
