Why is my ZTS 7500 running slow and backfiring
I have a ZTS7500. It was moving slow and backfires when I dropped the blades down I checked to find the plugs black and filters clogged. I changed plugs and filters kit. Not much change when dropping the blades down. Still rolls slower than normal and backfires. Oil level is fine. What do you suggest?
