  1. @MagicCadillac It's always easy after you do one time. It took me a second to get used to how it works again. I don't adjust these very often. Its pretty new to me.
    I started it up again last night, and no smoke!! Thats a quick 30 bucks in my pocket! Too bad its for a friend, or I would have charged double that amount.
    Thanks much bud! πŸ™‚

  2. @edzgarage Thanks Ed! I don't think they're gonna want the whole thing rebuilt. I think it has a leaky head gasket, and oil is dripping into the exhaust. She runs fantastic right now though. Its already gone, and I've been paid! πŸ™‚
    Thanks again Ed!

    Thanks bud

  4. @pyrophilster I set them in the middle. Its supposed to be between .004 and .006, so I set them at .005.
    The engine runs great now! Its out the door, and I've been paid.
    I think the Bears need a little work…..This won't be their year..LOL! The Eagles are not all that either, but there are so many tough teams right now.
    Those Lions are gonna kill my Bears tomorrow night!
    Thanks much bud

  5. @cameramonkey2 Well, the bottom line is, the owners didn't take very good care of this tractor at all. Its in really bad shape. I offered to buy it for $100, and they are thinking about it. I'll take that engine off and scrap the rest of the tractor, because to be honest, its not worth much more than that.
    Thanks much bud!

  6. @More350Power The smoke was from oil leaking down into the exhaust. After a few minutes of running, the smoke cleared up.
    Thanks much bud!

  7. There is an allen head in the center that needs to be tightened in order to lock the valve adjustment. If that keeps coming loose, try some blue or red thread locker. If that doesn't work, there is something internally wrong with the head.

  8. Hi Have a question about john deere with a B&S 19.5 HP engine. The valves were worked on before i adjusted the intake valve ,I noticed a small cap on the exhaust valve stem that makes contact with the rocker arm , there is'nt one on the intake valve stem ,should they be one? Thanks for the help.

  9. I wish I could see what you're talking about. The rods that go to the rocker arms are just rounded. There really should be no cap. I honestly would have to see it before I could decide.
    Sorry I'm no help right now. I would assume if there is a cap on one side, there should be one on the other side though

  10. I got a pic of the valves on my youtube , note the top valve between valve spring and rocker arm ,look at the bottow valve . Thanks for helping

  11. It looks like whats missing is the spring "keeper", or the retaining clip that keeps the spring from shooting out. You will need one of those!

  12. Dude you have to hold your Β torx in place then snug up the nut with your box wrench or your will not get the correct gap.

  13. where was the part where you actually replaced push rods?Β  do they just drop in?Β  that's why I watched in the first place…..
