Hello. I have a new Honda Model HRX217HYA with hydro drive and pull start. When trying to start with the throttle at FAST and blades disengaged, drive speed at zero, all as instructed, the engine kicks back. It is as if the engine pre ignites or back fires and pulls back on the pull rope so hard and quickly, I hurt my hand. I removed the spark plug and found it to be dry. The engine turns easily with the spark plug removed. This is the second time I have tried to use the mower. The first time was on April 21 when I received the mower and it started fine and mowed the lawn without issue. I changed nothing between that use and this attempted use. Any ideas?
Thanks,
Lyle (papazig)
