Oh.... I like that.....

Oh I figured someone would when I found it... I linked it on the G-Team G-Sources page so you don't have to search all over the forum for it too! Right down there in the Resources Section just below the Briggs link for these kinda goodies. 

Unfortunately, I was not able to find anything anywhere on the ohv691ep bore and stroke I was searching for, so this was as good as 20 - 30 minutes of searching got, except for the contest for the oldest ice auger or snow blower, which I assume you have neither down there to batttle skeeters with, eh! But, I thought some of our Cananadidian and Wisconite followers might, so I posted it here too!!

I I remember correctly its the same as a tvt691 or vtx 691. Only differences I have seen in any are carbs and sheetmetal and cam gear material.

Somewhere around here there is a gentleman seeking that wisdom if you by chance have it handy, because I wasn't able to find any drawings, nor any technical data that include bore and stroke. Found all sorts of data on it, I found drawings on it, but not the information he was looking for!

It's good, and I was looking for something like that before. Now we need the bore and stroke page to go with it.

I looked at a snow blower...... we have something bigger.... chunks manure in the fields..LOL...
And the ice auger... post hole diggers for the ice... who woulda thunk....

   The bore and stroke for all 691 V-twins is 3.125" (79.375 mm) bore x 2.75" (69.85 mm) stroke producing 42.18 cubic inches (691 cc).  All the specs for this engine are found on page 10-1 of the Tecumseh V-Twin Engine Technician's Handbook, Form No. 696325 1/2000.  These manuals should still be available.
   This is a great engine!  I have a 25hp OV691EP on my custom rear-engine yard tractor with an 820 transaxle -- best project I ever built!
