Honda had a recall on the early VXA models. The symptions you are describing sounds like that is the problem. I had a VXA and Honda fixed it under the recall(Honda called it an upgrade). If I were you, I would contact Honda with my serial number and see if yours was included.

Thank you LMY,

Do you know where I can see 'upgrade' info for the mowers ? I've been to the hondapowerequipment website and looked at the recalls, but the only one mentioned there was a fuel tank issue that I've confirmed did not effect my engine. However, I want to say that I read some time ago online that Honda had released an 'upgrade' to the spring in that thumb actuated speed paddle also (to require less pressure). Do you know if that is true, or where I can verify online ? I'll definitely be calling Honda tomorrow, just hoping to have as much info onhand as possible when I do.

Thanks again.

Let us know how it turns out

Both the thumb control and blade lever have upgrades available. I doubt either are listed on the consumer web site because they don't want everyone rushing in thinking they need it when they don't. Many folks have no problems at all and since neither is a recall no notice to the consumer is required.

You've had the mower about two years according to your post, Honda is real good about recently out of warranty stuff regarding covering them. If you are out of the 2 year warranty, go ahead and take it to your local dealer and ask them to contact Honda about getting approval on having either of the upgrades covered.

How can I tell when my Honda mower was manufactured? I bought it used in good condition. The owner said it was two years old but I think he fudged a bit.
Model Number HRR2163VXA
Serial number MZCG7231537.
I think I got good value for the price but I would like to know how old it is.
