So I was given a John Deere 828D (5-6 years old) from my mother-in-law (long story). This is a classic dual stage, gas powered blower (8hp Tecumseh engine) with a 28 inch path. I used it for 2-3 storms last winter, used it to blow 1/2 the driveway yesterday, turned it off, went to start it again 2 hours later, and couldn't get it started. Even though it had only been 2 hours, I still primed it (3x), pulled the rope, it started and died real fast. Then it wouldn't start again. I immediately smelled gas, so I assumed the engine was flooded (shouldn't have primed it). I left it for 20 minutes and tried again. 10+ pulls... nothing. Left it for the night and shoveled the rest by hand. The next morning (this morning), didn't prime it... 3 pulls (nothing). Keep in mind, this blower always starts on the first pull! Primed 3x, 10+ pulls, nothing. Brand new gas, have never touched the idle screw. My question is this: Why would it always work great (first pull), then 2 hrs after using it, not turn over? Could I have fouled the spark plug after flooding it to the point it wouldn't recover 12 hrs later? I'm thinking it might be a clogged fuel line, because a) there was a little bit of gas from last year in there, and b) when I press the primer now, I get a hollow sound (like blowing into a straw). Should't there be little or no sound from the priming pump?
