Honda HRX needs tachometer adjustment from factory?
I have been looking for a new lawn mower and came down to the Honda HRX vs the Toro Super Recycler. Was leaning towards the Honda HRX and went to a local small engine store to look at their inventory. The salesman told me the Honda mower came underclocked from the factory and they have to hook it up to a tachometer and adjust the engine in order for it to run at optimal RPM's for mulching, cutting, etc.
They sell the HRX with blade brake for $729.99, no discounts or sales. I can get the same model at home depot for $699.99 and also get a 10% military discount there, so about $100 difference between the small local store and big box home depot.
My question is does this make sense or is the salesman just blowing smoke? Is it worth $100 price difference to get the engine tuned up right out of the box?
Thanks for any info you can provide.
