I have a Troy Bilt Briggs & Stratton 6.75 hp self propelled mower that's only about 2 years old. It ran great last season and then we moved and it rode on the moving truck tipped up on it's nose for a few days. I had ran the gas dry before we moved but the oil was still in it. There was a big oily mess when we unpacked it. Now that I'm trying to get it running, it will start but idles really low and then eventually quits. I'm using new gas with stabilizer in it, all the oil had ran out so I put new oil in it, I got a new spark plug, I took apart the carburetor and cleaned it and used carburetor cleaner. I also used an engine cleaning additive that you ad to the gas. I think it was a "sta-bil" quick start stuff. What else can I do? I'm trying to avoid taking it to the shop and spending what I could spend to get a new one. It would be great if I can fix it my self. Thanks!
