It’s 42 degrees, so I don’t think it’s heat. However I have replaced carb, fuel pump, air filter, fuel lines are wrapped in heat shield, fuel pump is wrapped in heat shield, inline fuel pump was installed by fuel tank.I took outer rv door, not generator cover off.That didn’t help. Any is help appreciated.
