Pap, I've got money and the fuel line. I bet a loose clamp at the primer bulb or bad primer bulb. This is a 4 stroke yami. Never seen ethanol in 4 and half years I owned her. Fresh carb clean last spring. Also water separator changed monthly. I bet she's sucking air. Before you even start it bill. Pump that bulb hard. See if any fuel leaks. I'm sure you will see the problem if it does. I've replaced the line before. That motor is a champ. Rule the fuel issue out first. The connection to motor could even be sucking air.
You don't bother me. She's a fishing machine. I'll do what I can to help
