getting ready to put boat back in the water. Last time out last yr, engine would not run. Left the dock fine and about 100 yrds out shut off. would Start fine and shut right back off. Over the winter, I rebuilt all 4 carbs and fuel pump, replaced water pump, decarborized (#1&3 cyl much worse with carbon build up then 2&4). Now, will start and runs longer however smokes really bad and left oil all over the ground behind / undernieth it. While runnung it "misses" / pops and blows more smoke. first thought: oil mixture too rich. Won't stay running too long ~5 mins or so. When trying to increase throttle, boggs and does not respond as expected.
Any suggestions?
