I just installed a new Rotec TBI unit on my aircraft. It was carbureted but I wanted to clean up the lower cowl area and install a 90 degree elbow to mount the ROTEC TBI to. I am talking about a RUTAN LONG EZ. I need this forums help with troubleshooting the issues. The unit seems to be starving the engine of fuel. I checked flow prior to the diaphragm. it was almost 20 GPH. I have checked the finger screen and it is clean. The unit will not allow the plane to idle below 900 RPM I need to have the mixture FULL RICH and the throttle open about 20%. The engine is chugging and stumbling like it is too lean. If I attempt to pull the mixture even a little bit off full rich the engine will die at any RPM. the 0320 runs extremely rough and struggles to maintain any RPM without choking for fuel. I was able to get 2400 static out of it today but I could not move the mixture lever off full rich or it would start popping and chugging for fuel. Even at 2400 WOT the engine was running like it was way too lean. It has a lightspeed electronic on the top and mag to support bottom ignition. I am running 100LL AV gas. When it was carburated it ran like a clock at any RPM, smooth.

Does anyone have any experience with the ROTEC TBI on a Lycoming engine. I need your help to resolve this issue. I have plenty of installation pics to review. I have a ROTEC 40-4 unit.
