------Im no expert but it sounds like your engines are running lean. Fix it and fatten up the secondaries some, and also get more input than just me (LOL). I still have a valve out of my old Mistress (twin 540s) thats at least a quarter of an inch longer than when it was new. Did just what yours did and the miracle is that it didnt break off and destroy the whole motor.......Bill S

Don't have fast burn heads, So I will see if I can ajust the carb, maybe bigger jets, don't know much about carbs only that they are 750's holley, I do however have a box of Jets that came with to boat, I'll have to see what is in it now and maybe step up, I think you go two up or two down? but a good place to start. Thanks, Fast Frank

What do you have for ignition boxes on this boat? Do you set total or do you set initual and add the boxes to it? Also how did you adjustt the valves? All food for thought. And do you have vacuum secondarys or Mechanical?
