The engine has been gone thru by a dealer. All compression is good and supposedly has had a carb rebuilt done to it. My Question? after having the engine warm, when idling down, like going thru the harbor, it will eventually load up and die., Sometimes it starts right away, other times I need to rechoke it and then it starts. Also after idling down, it seems to have a higher idle rpm for a minute or two but the makes a "popping noise" then idles down, it may keep running but sometimes also dies? Any advice? Could it be a fuel line problem, like not keeping enough pressure?
