Tiny tach miss reading

Recommended Posts

richp
I installed a tiny tach on my 4040 with Onan twin. It worked on another tractor I had but now it reads real high. At idle it reads 3200 rpm's and at top speed, over 4000. I know it is running way under these numbers by sound. I have the wire that is spiraled around the plug wire on just one wire. I think I have a good ground to the block. Anyone else have a problem like this?

I think and D17 can correct meif I'm wrong. But doesn't the onan fire on both cylinders at the same time, whether it is compression stroke or not. Probably not worded right either

      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
