WOW Marty,how many gallons did you have ahead of you? Sitting on fence here,leaning primarily towards the done for season side.Last sap out of the tubing was pretty milky,kinda thick and smelled,boiled it down,still making an old medium syrup,stronger flavour but not yet buddy. Ran vacuum pump all day on one bush on Saturday,didn't pull in much sap,pretty cloudy,thought I might clear the lines out and dump,then see if a fresh run would clear up,got to the main bush and could smell gasoline before I got to the generator. Needle valve or something is stuck allowing gas to flood right through onto the ground,so will have to get that fixed before we would ever fire up again. Maple Weekend Open House here this weekend,whether to boil water,or might get lucky with sap,but it will definitely be water if sap is poor,don't want that snotty stuff going through the pans.
