I've been brush mowing with a new to me 860. Tall grass, weeds, etc. After about an hour and a half or so, the engine starts sputtering as though starving for fuel and the sediment bowl that is mounted at the carb has vapor bubbles coming from the supply line. I shut it down to cool off and could hear the gasoline boiling inside the tank. This does have the under-hood muffler. I'm thinking that whoever replaced the fuel line between the tank and carb has the routing wrong, possibly undersized and that there should be some sort of insulation between the heat shield and the bottom of the tank. If anyone has suggestions or experiences with this, please share them.
