I have a DA50 that had been running great, it 1st began to not run well, and over time it got worse. After rebuilding the carburetor by the recomendation of desert aircraft, it will now start and ideal just fine but when I advance the throttle it dies. I have adjust the low and high speed needles back to factory settings and then tried to tweet them to no success. I can get full throttle if I chock it just right. (Choke partly closed)

I am out of ideals, anyone have any suggestions?
