Stuart engines: #7a vs. #10v
« on: December 12, 2014, 12:28:33 PM »
I recently sent a message to a guy selling a 7v on eBay to inform him of missing parts.  Doesn't seem to have affected the sale, as the price is north of $150 and climbing with 2+ days left.

I purchased a 10v (also eBay) about a year ago.  Looks to be nearly the same engine.  I know that the 7a is slightly larger; 7.5" tall vs. 6" for the 10v. 

I assume is has a correspondingly larger bore and stroke.  Other than that, what are the differences?  Why is the 7a so much more expensive than the 10v?  the web searches haven't been much help.
