5212.5 Throttle Question

Recommended Posts


Hi All,

I've been able to get this Craigslist 5212.5 running and mowing, but I'm wondering if anyone can advise what might be wrong with the throttle.  The RPMs barely change as I move it between "rabbit" and "turtle".  It may be hard to actually see in this video, but the governor linkage moves throughout the motion of the throttle lever, but the lever on the carb only moves in maybe the last inch of movement as the lever gets down to "turtle".  You can hear a little click in the linkage as this part moves.  It looks like all the pieces are there, but I'm wondering if something is missing that im not seeing or adjusted incorrectly by the previous owner.  Any ideas?

First make sure you're getting plenty of fuel. Once you've determined that check to see if the butterfly in the throat of the carb is moving. This should get you started. If this all checks out then it would have to be inside the carb.

Belated thanks to SPI for the above reply.     Closing out an old thread issue here.  

I had been just ignoring this issue and continuing to use the tractor, but recently noticed in a parts diagram that I was missing a gasket.  I added the missing  gasket that goes between the air filter box and the carb and now the throttle works great.   This also has resolved issues with flooding after stopping and trying to restart the engine.    Sharing here in case anyone else hits this.   Thanks!

      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
