Almost lost the Twinstar a few months back. The engines are TT .36's. One died and the other started boggin down. They had quite a bit of time on them flying off grass. Since then I've taken the engines apart and cleaned them in a sonic bath paying particular attention to the carbs. All back together now and have run them in on the test stand. Now for my problem. One tops out 2k rpm higher than the other. When matched pretty close at the top and idle, they are nowhere close in the mid range. They both run independent great (excellent transition), just not together. They used to run perfectly together. Any ideas. I'm planning on putting them in a TF DC-3 eventually.
