I had the secondary injectors flood the engine during ground testing.  It was caused by a short to ground, a wire got pinched between an intake manifold runner and the top of the engine so it grounded the injectors and produced a continous flow.

Subject: [FlyRotary] fuel injection

Tracy, this morning I got the Tailwind out for the first flight, started it up and every thing looked like a go, the wind has finally subsided.  Went to the house to tell my wife and went out to go.  On start up the engine was flooding bad, so I shut of the primary and secondary injector switches and the engine leaned out enough to stay running.  From past posts it is my understanding that the injectors are activated by the ground, is this correct.  This is the same way it acted last fall when I changed the injectors, some thing is causing them to stay open, apparently when things get up to temperature and it sits for a short period of time.  The wiring harness is one of Bob Whites and is wired according to his diagram, which I have checked several times.  I noticed that the mixture and program knobs do not function with the injectors switches off.
 
If I pull the fuse to the fuel injection system, can I fly on the Weber carb, it runs well with it.  If I can get the 40 hrs flown off, maybe I can get it down to Mason and have David check it out, as is beyond my capabilities.  JohnD
