[AT] Coil test?

[Dean VP]

Ralph:

Ok, it looks like you have by process of elimination cleared it all the way
to the carburetor. What hasn't been proven is whether the carburetor is
really ok. Since you have a spare coil it will be an easy test to replace
the one you have and see what happens. 

My gut still tells me it's a fuel problem, but now just in the carburetor.
Maybe one of the passages is partially plugged. Does your carburetor have an
inlet screen to keep stuff out? Maybe when the tractor is working it stirs
up the sediment and some of it makes it to the carburetor. Then clears when
the tractor sets awhile. 

I hope the coil solves the problem so you don't have to mess with the
carburetor. Too @#$% cold to do that kind of finger work.

Dean, up until this evening I was about 50:50 between ignition and carb
problems. Now I am leaning more toward the coil being the problem again.
Just before dark I went out determined to check if fuel was flowing to the
carb. And yes, I do have methyl hydrate added to the tank, sediment bowl is
clean enough to drink out of as is the screen.
So I unscrewed the load needle from the bottom of the carb and turned on the
valve at the tank. Gas flowed out in what I considered a pretty good stream.
I doubt the engine could burn it up that fast.
The only spare 6 volt coil I could recall was on a parts 40 in the bush, a
good long walk through sometimes knee deep snow at -18 degrees but I figured
I needed the exercise. Sure enough, there was a coil on the parts tractor
and after a struggle with only a pair of vise grips in the semi darkness I
was able to remove the coil.
Now this parts 40 falls into the "running when parked" category and I have
no idea just how good it's coil will be after sitting out in the elements
for close to 20 years.
On a quick test with my cheap digital multitester it showed 1.3 but I
haven't tested the one on the "running" tractor to see how it compares.
