I bought the yard works push mower 60-1620-4 a month ago. It will start on the first pull. I will do the entire lawn no problem. I go to the next lawn and it won't start. I have been doing lawn maintenance for 25 years now and I have never seen this. Canadian Tire won't help me and the local shop will not look at it at all. New gas and oil in it and I don't flood it.
