"BIG" upgrade for a little sled! the kitty cat gets a 4 stroke Briggs and it Ripps!!!!

a friend brought me this little sled as a project. his buddy bought it for his kids and never got to use it cause the stock 2 stroke motor wouldn't run and it is pretty hard to get parts for these days. so I swapped it out for a Briggs and Stratton 6 horse motor off an old pressures washer I had kicking around. I gotta say it turned out pretty awesome! and now if anything ever goes wrong with the motor he can get parts for it no problem!
