'78 volvo aq130d(4cyl)/280outdrive twin solex carbs, 18 1/2' tri-hull(paul emerson boat from costa mesa, ca). when i go to pull my kids skiing, upon initial acceleration the engine bogs down, will almost die when i floor it. i can kind of nurse it thru this dead spot, but it just drags them. doesn't do it nearly as bad with no load. if you know any thing about this problem please give me your thoughts. i'm very do it myself and can probably fix this with your help. thanks again
