Help!,<br /><br />This motor, which was supposedly rebuilt a couple years ago, starts great all the time. It runs well on first startup, gets boat up on plane, and seems to run full throttle. If I bring it back to idle, or shut it off, once it's warm, it will restart fine, but bogs down and dies before accelerating. It restarts every time, and eventually by feathering the throttle I can get it back running, but it runs roughly at middle rpms, until it gets going. Pumping the fuel bulb doesn't help, have replaced fuel lines and tried different tanks with same results.<br /><br />Would a carb problem only manifest itself while the engines hot? It seems like a fuel problem, but could it be the power pack?<br /><br />Any ideas greatly appreciated....
