I took my 15-y/o MTD (Costco) mower in on a Friday afternoon. Pete warned me that he had several other mowers ahead of mine. He asked for the symptoms (wouldn't start; backfired) and that's all he needed. I told him I could change the oil and take care of the blade myself, and he respected my request to leave those items to me. Next time I'll let him do it all.
