I had a funky problem on my '72 Cub backhoe, "Bugs". I lent him to a friend, and when I got him back, the comment was, "it will always start if I get things just right, and hit it with a shot of starting fluid...."
I had never had this problem, though at times, Bugs could be temeramental to start. I remembered, also, that sometimes the engine seemed to ctach and start start as I released the keyswitch from the start(cranking) position to the ON position.
I did a little detective work with mty friend Alex, and sure enough, the ignition switch was faulty-it would "almost always" not supply any voltage to the coil, while cranking. Then on releasing the switch from the "Start" position, it would "almost always" begin to supply the 12V to the coil. the condition started out as very intermittent, and has gotten worse over the last few years. I had never seen this problem described on teh board, so I wanted to pass it on in case someone else has a similar problem.
So I wanted to replace the switch. The one ion teh tractor was not stock, and I didn't want to pay the $35 that a stock switch would cost, so I checked out Tractor Supply, and they had a Universal switch that looked like it would work, for $14.99, in the "tractor" section of the store.:
http://www.tractorsupply.com/agriculture-farming-ranching/tractor-tune-up-repair/tractor-tune-up-parts/tractor-electrical-system-parts/universal-start-switch-with-2-keys-1831705
I picked one up, and on a whim, I checked in teh Automotive aisle, and found there a very similar-looking switch, with the only differences being that the Automtive switch was about 3/8"-1/2" deeper overall, and it only cost $7.99. I can't find this switch on the TSC website.
I didn't buy the cheaper switch, as I couldn;t recall how much clearance it needed behind the dash, but I wanted to pass on that after installing the $14.99 switch, I am certain that the $7.99 one would do as well, and would have no problem with clearance.

I have an excuse. CRS.

Re: Keyed ignition/start switch
I've used a lot of the switches, like the one you linked to, I usually pick them up at swap meets. they work quite well. The next time I'm in TSC, I'll look for the other one, just out of curiosity.

Re: Keyed ignition/start switch
And after burning through my second Tractor Supply switch in 2 years, I bit the bullet and bought a real one! Now I just have to find time to install it.........

Re: Keyed ignition/start switch
I thought key start was later than 73??
Pretty sure the wrong key switch is the problem on my 70...

D'oh.
You sure it doesn't open a wormhole when you turn it to the on position?
