Brand new Lycoming IO 360 from Vans on first start on my new 7A. This is my first experience with a fuel injected engine. Standard Vans Airflow Performance boost pump and Lycoming Precision stock fuel injection. Engine run only at factory. First if I leave the fuel injection boost pump on for more than a couple of seconds fuel flows briskly out the manifold overflow. Pressure shows up to about red line, about 40 with pump on which appears to flood engine. Will start then by cranking with mixture to cut off. Runs fine once cleared above 1000 rpm on engine fuel pump but will not idle being very rich and floods out unless mixture is pulled back 1-2?. Pressure from engine fuel pump also showing high 30s. Fuel system flows almost 1 gallon per minute on boost pump at either level or in climb attitude. Seems like there should be some type of pressure regulator.
Need to fix before taxi tests. Where to start trouble shooting?
