Help..It's me again

Recommended Posts

Thanks for all the other tips. Now I have another problem today. Went to start the 4040 with Onan 16 1/2 HP engine and she wont stay running. When she turns over and I release the key back to the run position she stops. If I turn her over and hold the key in the start position it continues to run, but once I let go and the key goes back to the run position, she stalls. Any Ideas?? Thanks

It sounds like you could have a bad ignition switch. The ignition might be sending a ground to the coil and shutting it down. That is just one possibility, another is a short in your wiring harness somewhere shorting to ground. That is just where I would start looking. you can find the wiring diagrams under common questions. Oh and it would be a great idea to get out your multimeter before you start troubleshooting.Have fun Josh

      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
