Identify this motor for me please

Hey guys been lurking along time just now joined up ! I picked up 2 motors yesterday on craigslist for 100 bucks for both. Now after doing some internet searching I'm finding conflicting ideas , Some say they are 3hp and some 5hp . I know they were sold by sears but after that I dont have a clue haha . The chassis # is 217-5841-0 and serial number is 5A-166301. I need to find a manual for them as I broke the pull cord last night starting one. One of them runs like a top btw. I searched the links provided here for manuals but they arent very thorough.

any pictures?

i can post some up later but i think Ive got it figured out now after typing the right chassis # into the sears part search its a 1975 5hp sold by sears made by eska , good thing is it doesnt have solid state ignition!!!!!!!!!!!!!! still would like to find a manual if anyone knows of where to get one.
