My Generac 3500 XL was running fine last month. Now it starts up, runs smoothly only if about 45% chocked and then the low oil light comes on and it shuts down. The oil level is fine, but I changed it just to eliminate problems with the old oil. Admittedly it doesn't get much run time. We used it for several hours last month and we did fill it with fresh gas then. If the oil sensor is bad then how do I replace it?
