took the 39 to church today, on the way their it started to cut out I turned around and headed home and it got worse on the way home, after I got home I shut it off, then started it back up, it was a little hard to start but it did, it idle ok but then I heard it miss a little, I cked all the plug wires all on tight no loose wires, it has a full tank of gas, air temp 60, water temp 180, 39 ran strong yesterday around town, do I need a fuel pump? thanks sherwood
