I purchased one week ago a Toro 22” Recycler Mower, 163cc (21462) equipped with a B&S engine (m/n 104M020010F1). It was filled with new gas, oil topped off, and started great right out of the box. It operated perfectly over the course of two days (3 total operating hours) until it started to sputter. I refilled the tank thinking it was out of gas. It never started again.
I returned the mower and exchanged it for the same model. Again, it was filled with new gas and started great right out of the box. It operated perfectly over the course of two days (3 total operating hours) until it started to sputter. It still had about an inch of gas left in the tank, but was refilled anyway with new gas. It never started again.
It is important to note that the mowers are new (no carb or spark issues), gas is fresh, the mower did not bog down until it started to sputter, and it did not strike any objects.
At this point I am returning the mower and getting a different brand (very unhappy with Toro “support”). It is, however, driving me crazy as to what could be causing the same issue on two different mowers. Any thoughts?
