Fantastic! Thank you very much. I see they throw an extra A on the end but I'm not going to quibble.I think that translates to HRX217K4 HZAA with serial number range of MAGA-1900001 TO MAGA-2369999.

Yes I understand but for some reason there's an extra A at the end of the model number when you go to look up parts.A = America
Usually found on imported models because the locally made ones are all for the USA & Canada ( AFAIK )
Yes. For this mower the engine is considered part of the mower itself. Honda is a little different than other manufactures as that uses various engines as they purpose build an engine for this mower.Fantastic! Thank you very much. I see they throw an extra A on the end but I'm not going to quibble.
I do have a follow up question if I may. Some of the parts are different depending on the engine serial number. Is the serial number that is shown next to the model number for the engine or the mower itself? For instance my serial number is MAGA-2293810. That is for the engine? I didn't see any other significant numbers on the motor housing itself.
