This has been an ongoing situation for me since the plane started flying. At first, I made a cork gasket to put between the Precision Airmotive Silver Hawk EX and the FAB plate (.090) I made but the compression of the bolts that hold the plate in place against the gasket resulted in a depression on the plate and, ultimately, cracks around the edges near the washers. And the cork was pretty damp too.
So at the annual this year, I went dry.
This was right after I changed the oil and rolled the plane out to start the engine to check for leaks etc.
I had just taken a paper towel to the FAB plate to gussy it up. As you can see there's fuel leaking out between the plate and servo.
I'm GUESSING that this occurs when I have mixture and throttle full open and hit the boost pump for five seconds, as instructed by Mattituck for the engine. But it's only a guess.
How serious is this? And what are the solutions to having a better seal here?
BTW, for no particular reason, when I shut down the engine, rather than pull the mixture, I shut the fuel valve off in the cabin and let it die.
