As this conversation continues? a way to check your existing fuel system is set up properly? After you have got onto the lake and made a lap or two your fuel system should flow enough fuel to richen the boat up on a FAT Needle at High piston speed. If it cannot not? you better start to look at it. This means you cannot maintain a high piston speed & fatten the engine up too. This is going to be a Problem when you try to Run Wide Open Throttle Loaded with prop.... If you are Miling Rich and Happy And an medium increase in throttle position the engine seems to COME INTO ITS OWN NEEDLE?? STOP STOP !! ITS RUNNING OUT OF FUEL........... THIS is a Perfect example of its fixed to Burn Itself Up. This is a Must Test before you even think about leaning it down. A topic we had eariler in the week was about Reading the Plug........ I HAVE NEVER SEEN A ENGINE EAT A PISTON THAT WAS GIVING HAPPY PLUG READINGS. If this does Happen? Look for what changed?? Cracked fuel inlet line No pipe pressure or Cracked & Burnt header orings..... Normally the Glow plug would have been already Warning the driver that something was wrong with the boat!!
