Hello! I have a 1991 bayliner. I put a 1992 chev. truck motor in to get me through the summer while I rebuild the mercruiser. The trouble I am having is the engine runs and idles great. Takeoff has excelent performance, top end is perfect but when I back down to mid throttle it goes to sputering. I changed out all the gas. No change. Changed plug and wires,no change. Changed timming to 4,6,8,10&12 deg.BTDC @ 1000rpm,the only change I seemed to have was the top end began having a sputering at 12 deg. I need to know what the timming should be and at what rpm to set it at, also what the problem could be. Thanks for your time. ![Confused :confused: :confused:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
