Ok thank you for your advice but let me explain what I have done so you have a correct idea of things. I have complety disassembled the carbs and cleaned them, compression test @ 105 PSI on all three using Two test guages on three different tests. sync the carbs and set all linkages to factory spec. Used dial indicator to get #1 TDC and set timming pointer, set idle speed @ 800 Rpm with timming @ 8 degrees ATDC, aligned markes on CDI with Idle stopper and the WOT stopper, New NGK plugs set @ .035 and spark test @ full throttle position using a 7/16 gap results very good Blue spark. New fuel pump, All lines from new fuel tank and all new lines on motor with new clamps at all terminations.. So knowing all of this what am I missing to try or do other than to actually run the thing on the water and should I expect to get different results than on the trailer??
