I hope someone can guide me. I have twin 327Q's both were re-built approximately 150-200 hrs ago. The starboard engine had the carb re-built twice by the previous owner due to stalling.
My problem seems to be one that is common. I run the boat for a day on the river and both engines perform perfectly. The next time I use the boat my starboard engine stalls as I idle out of the slip. It seems to happen when I reverse the engine to turn the boat. After the stall it takes a few minutes before it will start again.
Now I've read many entries on the web page and I believed it was a fuel flow problem. I changed the seperator and the stone filter in the carb and this will seem to fix the problem for a short while but the problem returns. Recently I switched the starboard engine over to the port fuel tank running both off of one tank and had a great day on the water. I figured I cured the problem and I would empty the starboard tank and get it cleaned out. But guess what happened the next day. Stalled out again when leaving the slip and my wife and I had a hell of time keeping the boat off of my neighbors anchors due to the breeze.
I'm out of answers and don't know what to look for next. Before I rip off the carb I turn to the knowledge of those who came before. Any guidance would be greatly appreciated.
