Lots of excuses why have not got it back in earlier since since Bruce Turrentine went through it to see why the cranking compression was so low. He found blow by on the side seals , but could not explain why. It now feels much more like others when you swing the prop through. It did not start right up like I hoped now that it has better low rpm compression. Pulled plugs from both rotors and both were wet. I noticed that when leak checking the fuel system before cranking that the fuel pressure immediately went back to zero. Suspicioned that an injector was leaking but ruled that out since both rotor's plugs were wet after trying to crank. Checked the rate of fuel pressure decay after shutting the fuel pump off both with the injectors on and disabled. No real noticeable change. Any suggestions?? My memory is correct that the fuel pressure stayed up a relatively long time on shutting the pump off before I had the engine out isn't it?? Bernie, maybe I'm too old fashioned to get all this electrical stuff to work :>( ----__JNP_000_6dd7.2adb.3fc7 Content-Type: text/html; charset=us-ascii Content-Transfer-Encoding: quoted-printable
