I was having problems at idle. When I would put the motor in gear, it would die. I did a decarb, and turned the idle stop screw 1 and 1/4 turns bringing up the idle speed a little.<br /><br />Put the boat in the water, pumped the ball, and she fired right up. It idled a lot better, and allowed me to put it in gear without it dieing so off I went. She ran great through the no wake zone and really ran well at full speed. At out 4000 rpms, however, it felt like the speed was surging a little. I didn't notice that at low speed or full speed incidentally. <br /><br />When I got near the dock, I slowed the boat way down, and pulled it into neutral. It died. The only way it would start again was with the fast idle all the way up. When I would try to bring it into gear it would die immediately. My idle problem is back! After a few frustrating minutes, I squeezed the ball and it was a liitle soft. Once it was hard again, I tried to start the motor and it started right up, and allowed me to put it into gear (coincidence?). On the trailer it went.<br /><br />Okay, the question: Is this likely a fuel pump issue, electrical, or maybe a float problem in the carbs? It's a new gas tank, ball, and connection by the way. And the vent was wide open on the tank ( I know somebody was going to ask me that!)<br /><br />The fact that it runs so well and is so powerful at wide open throttle, makes this extremely confusing for a novice like me.<br /><br />What's next?
