I just recently pulled a plane out of the closet that i built last year but never got around to flying and have been trying to get the TT pro .46 to run properly. The plane has been sitting for a while with the engine only being run twice. So, now to the problems. First off, I recived the Thunder tiger pro and mounted everything for breaking in last augaust. The first times I tryed to run it it would start fine and run well around 50-60% throttle, but when I would get it up to full throttle the engine would slowly wind down and eventually die. This would happen every time that I would run the engine so I started to fiddle with the mixtures by richening up the mixture or leaning it up. But everything resulted in a full throttle wind down. Next I went and picked up new glo plugs and a fresh bottle of fuel but still the same thing happend. Currently I have found that if its runn sloberly rich it will stay constant and runn properly. So if anyone has encounterd this before or has any suggestions please enlighten me!!!!

Next, I have 6 oz. tank mounted right behind the engine. When the motor is running at speed the gas sloshes around the top of the tank and into the breather line and chokes the motor. But my question is how come when i remove the breath line that goes to the muffler the engine runs fine but when its connected it will choke? I am wondering if a new tank could help?

Thanks,
