I have a Honda HRX217K5VKAA model, serial number MAGA-2624469. One of the bolts that holds the deck ( I think) to the engine fell off. The bolt screws in from the bottom of the deck and comes out through the engine block. I tried looking at various diagrams to find the part number so I can order another one. I think the part number is 9012-VE0-000, but I am not sure. Can anyone please help? Thank you.
