Simplicity Sovereign 3415H

Recommended Posts

I have a 1972 Simplicity Sovereign 3415H with a bunch of attachments that I love, but it's time to rebuild the motor (15hp B & S) and I have been unable to find a kit or even parts to do so. Help!

I'm in the process of rebuilding the 16hp b&s out of my '78 7016 Sovereign. The engine is a 346431 cast iron single cylinder and was running fine until the top compression ring shredded and took the smooth cylinder walls along with it. I have been able to find every wearable part (i.e. not blocks, heads, cranks, etc) from jacks small engine online. You'll need to find out the engine block number and model type (usually a 4 digit code), and then download a parts list for it. Briggs seems to still make lots of parts for their engines, which is why I decided to rebuild rather than repower. I was able to find a complete gasket set, and a 0.020" piston set with rings and paid just over $100. Good luck....its pretty fun:) Spence

      folowing  this from a link at the downloads.  I just rescued an AC 920 with the lambodini diesel. I can' t download  yet .  Where did you find the PDF copy you posted. . I would like to figure out how to adjust the injection pump. 
      I assume it's a bosche, correct

        Over a year ago, you answered a question I had about the tool bar for my FDT. In your reply dated Dec 31, 2019  you said the spacer, part #16, goes in the bar to allow for up and down depth adjustment. does this mean the bolt has to be tightened at whatever depth desired or does the bolt slide up and down, allowing the lower hitch to free float?
         If it is tightened so the lower hitch and the bar are rigid, then is the depth to be controlled by the shoes? Or by the lift handle?
        Is there any kind of user directions for the tool bar? The Outdoor Power Manual basically shows how to assemble the bar but not how to use it
