Anyone have a link to specs on 2, 2.5, and 3hp Briggs engines. I just got 5 engines and 2 of the ones that have 2hp recoil covers also have had tank brackets bolted to the lower mount hole near the bottom of the block. They now have 2hp tanks, but there are clean spots in the grease where a tank with the lower bracket has been bolted on. Did the 2hp ever come with the deep tank? Will the 3hp tank fit the 2hp? A link to the specs will tell me the bore and stroke and I can go from there. Just trying to sort which is which.
