I’ve had this little guy for 8 years and it starts on the first few pulls every time. I use non ethanol fuel that has Stabil. Winters she is stored with no fuel in the tank or carb. My father in law borrowed it and incorrectly checked the oil. Thinking it was empty because he checked while it was sitting straight up, he filled it up to the dipstick. He said it ran but smoked a lot. I told him it never does that and that is when he told me he filled it with oil in it because there wasn’t any in it at all. When I got it back, I removed the excess oil, pulled and checked the spark plug, cleaned out the air box and filter that was dripping oil. I can’t get it going. Nothing, not even a stumble like it wants to start. Is it toast?
