What am I missing? I have a GTX that we just purchased. Test drove we’ll, launched it to take to dock, ran well first half then wouldn’t go past idle. I’ve researched all the ethanol damage posts. I’ve replaced all of the gray lines, pulled and cleaned the carbs with rebuild kit. It still won’t fire. It does if you drop fuel in the cylinders through plug holes but nothing is running through the carbs. Does the system have to be primed? I’ve read that the accerator pump does that. HELP
