If every thing been put back right it takes up to 5 hours for rings to seat , I hope rings not been installed wrong , as Briggs rings tricky .

One of the tricks is to let it sit for a week after the overhaul , then work it , assuming every thing been put back right .

What oil ur using ?

I'm using 10-30 reg oil. I installed rings per paper that came with the Briggs rings. I have been rebuilding 1 cyl to 6 cyl deisels in farm tractors since I was 14 yrs old, and never seen this much smoke come out the exchust. I am complety baffled. I'm thinking maybe I didn't hone enuff?

Two ways oil gets into the cylinder, valve guide seals and rings. If the cylinder was not round and straight, honing will not correct these conditions. Honing will only change the surface finish.

      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 
      Paul
