Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

I have an old ariens 5hp from the 70s that needs a carb and a gas tank, the frame is obviously still good.  I found a good deal on a newer tecumseh 5hp snowblower engine with a 3/4" x 2 5/16 keyed and tapped shaft.  Is this a direct bolt replacement for the older 5hp engine?  Unfortunately I can't look at my machine because it is a few hours away at my cabin up north.  Any help would be appreciated!

Thanks, I found him.. I am going to buy one from him and hopefully bring this thing back to life!
