sears tech. has tried to fix the same problem [stalling engine] many times. At least 5 in 2010. The last time was in November, when they put a new engine [accept for the parts he had to swap from the old engine] which has about two hours of run time. Since it has been more than 90 days. It is not the same case. I guess I was supposed to mow the 3ft. of snow to find out if it was fixed. Warranty ran out before time to mow again [3 weeks] Sorry, your problem now. You will have to pay for repairs. read full review »
