Help!

I need help from the small engine gurus on site. This is my small push mower at my house; a Toro with a B&S 122702 3192 01. Its been dying on my son after he uses it to cut the neighbor's lawn, where its run much longer than I ever use it her on my postage stamp. I suspected the carb (because I always suspect the carb) so I took it apart to clean & inspect and now in putting it together, the choke butterfly won"t stay open at WOT.

At idle position.

I can't for the life of me figure how the choke plate should be held open at WOT.  No effective difference between the 2 by the black lever (below the smallest spring at top).  Any input is most appreciated. Thanx, Dave

Possibly gets sucked open under vacuum

The spring pulls it there. These photos were with engine off. The spring is too strong for vacuum effect. Chokes and dies when running.

Going to guess that the wire with the spring that is hooked to the choke arm is too short, pulling the choke closed before it should.  Can't see the other end of it to see if there is another way to hook it that would make it longer.  The other option is that whatever that wire is hooking to on the other end is moving too fast and closing the choke.  Are you sure you didn't hook something in the wrong hole? 

If it worked before, it should work again, there must be a misplaced connection somewhere.

I know this probably doesn't help much, but that is my best guess.

It turns out that upon reassembly I bent the metal tab that contacts the plastic top piece of the choke plate. You'll notice it has a bend to it that isn't supposed to be there. I straightened it out (about a 60* angle) and now it works as it should. Thank you for your support., Dave

      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
