Re: 1978 70 HP Linc and Sync
welcome to iboats, unfortunately it is a step by step process, directions in the service manual. each motor, model and year are a little different. you need a service manual. have you check spark, did the person that did the carbs, remove the high speed jets, and clean them? that is the # 1 cause of your problem. also were the fuel lines flush out, before connecting to the carbs?
