Well I finished up my 5200 this past week. I decided to repower it after not being able to get the old 8HP engine to crank up after sitting for over a year. Thanks to Bruce and others for their info. Started off kind of rough. This is during the tear down phase.
Here i started to repaint the tractor with Orange and then later decided to go Red
Here is the 13HP Carroll Stream Engine
Here is the original 8HP adapter plate. I decided not to use this as it would have used 5/16-24 bolts to mount the engine and I wanted to use the 3/8-16 bolts instead to support the weight. Found a plate at Gravelyparts.com
Here is the finished tractor.
This is how I did the Muffler. Just a temp install till I figure out a better way that looks better.
