I had the motor running the other day . I was towing a dock from the ramp to my house I Made it about 3/4 mile then it coughed and died!!! now it wont start. I took carb off cleaned it . Changed plug. drained gas tank and cleaned it out. .Changed fuel filter. I changed the fuel lines . I noticed the fuel line at the base of the fuel pump was leaking to I put on a clamp. I am wondering if it might be the pump? Anyone have any clue what I can do .. Lobster season is coming quick!!!
