It was running fine until about the 3rd time I used it. I was running it and all the sudden it would bog down and die. It would run ok with the choke open. I researched and it looked as though the carb needed to be rebuilt. I ended up getting a 1976 15hp carb and rebuilt and installed it. I got a new gas tank and hose with the bulb to help eliminate the carb from getting more gunk in it. When I got it all together I stuck it in my trash can filled with water and it worked like a champ. Fast forward to about 3 days later, about to head out fishing. I tested it really quick to make sure it was all good and it would run for a minute then die. If I squeeze the bulb it will help it keep going and if its dying and I pull the choke out it will rev back up a little for a second or 2 and then die. I've tried adjusting the idle needle every which way and even if it does make a difference in how it idles, the motor will just die anyways. I did a little more research and found an old thread on here with what seems to be the same problem. A few people were saying its a bad fuel pump. I replaced that and it seems to run a little longer than it did before but ends in the same result with the engine dying. I'm stumped as to what I should do next, any help would be much appreciated!
