Hello Dan, Thank you for the question. Normally the model numbers are stamped directly into the blower housing, muffler heat shield, or a few inches above the spark plug. If you need help placing an order, customer service is open 7 days a week. Please feel free to give us a call. We look forward to hearing from you!
