I need some help . I have a 1996 sea pro with a 4.3 liter in board . :laugh: I have develop an issue . When the boat is away the engine starts back firing through the carb. But then it goes away and then comes back . It also now has run on . I have done the following set timing , replaced wire and plugs . Had the distributor work on last year and the carb rebuild about 2 years ago , It was running fine now this happen . I change RPM to see if that would make a difference but it still there . Thought maybe it was the coil . But why the run on and why the smell of fuel . I also change the fuel filter . Anyone have any ideas . Before I spend allot of money . I love the oat and fish her every chance I get . replace the fuel pump last yr.

Thanks
John
