The ID numbers would have been on the blower shroud but the shroud on your engine does not appear to be original to it. It has the raised fins on the cylinder head and the rearward head bolts are beneath the tin covering on top so to me, that would ID it as a 16hp because by the time they switched from having the bolts through the top of the head, I think only the 9, 10, and 16hp were still in production and the 9 and 10 had a completely different style of cylinder head cover than what is on yours.

The raised cooling fins on the cylinder head indicate B&S 16HP. You can also remove the cylinder head and measure the cylinder. 16HP standard bore is 3.5615-3.5625". If the top of the piston does not say anything than it is standard piston or it may say 0.010", 0.020" or 0.030" which would indicate the cylinder has been bored oversize.

When I got this machine it had the different shroud and I assumed that the engine was a 10 hp. The picture shows the shroud with 16 hp. 

You guys are my heros! 

This is a great club!

      Hello glad I got on this site. I hope to upload a couple of photos of my Simplicity Broadmoor 
      Model 707 Tractor. I have replaced all the belts on it and installed a new ignition switch.
      Have a mower deck which was in poor shape , repaced a couple of bushings and welded the
      deck where there was some holes. The tractor and mower deck came from a friend and the 
      mower deck metal was getting pretty thin. Some new metal was put in it and we also undercoated the underside of the deck. This was done by my friend Greg Toulman.
      I have not put the mower deck on the tractor yet, waiting for Greg to come home and give me a hand. Can you please tell me if there is a manual for the mower deck and where I could get one.
      I would also like to get some moon wheel discs as well.
      I will try and down load some photos of the tractor when my wife shows me how to. 
      I really love driving this tractor and also how well it is made compare today's tractors, especially the flexible rear end and the rollers.
      Tell the next time
