I received my engine on time. It is working great and easily installed except the muffler did not exactly fit the frame of my Troybilt Horse XP. However it was an easy modification, I just had to notch a quarter inch out of the right side running bracket of my frame. Took an extra 5 minutes and then the engine popped right in. Wiring was simple with the provided info. Everything was perfect here. the salesman was great and the overall experience was smooth and easy. I would highly recommend using Small Engine Warehouse for your mower engine needs. Great Job Mates.
