TimWafer said: (quoted from post at 18:23:33 01/04/10) I installed a Pertronix ignition on my Skid Steer about a month or more ago. I used their flamethrower 3-ohm coil and all seemed fine at the time. In fact it was running great back when it was warm! Haven’t really used it since then. It just has a little Wisconsin V4HD engine in it by the way.
Yesterday I need it because my diesel tractor gelled up and we got about a foot of snow and I needed the skid steer as a backup to dig out.
It started initially but was pretty sluggish which I attributed to the cold. Usually it warms up in a few minutes and is fine but it seemed to get worse and eventually seemed like only 2 cylinders were firing. I limped it back to the barn and found that pulling the plug wires off either or both of two of the cylinders had little effect while doing the same on the other two made it die or nearly die. Also noticed that the spark would jump at least a half-inch on the two good cylinders while barely noticeable on the two weak cylinders. The plugs are new and I set them to .035” I replaced the cap & rotor today since I saw some moisture underneath. None of that helped the situation however and I’m getting frustrated. I guess I can replace the wires next unless somebody has another idea what the problem might be. Couldn’t really see any sparks leaking from the wires in the dark but doesn’t mean there isn’t.
I finally got the tractor started after replacing the filters and bleeding the whole system so I’m not desperate at the moment but it is still snowing.
I could be way off base, but "good spark on 2 & nearly no spark on other 2" sure doesn't sound like a EI module problem, but a spark distribution problem. Kinda brings to mind an old song, "Lookin for......in all the wrong places'.

Today's Featured Article - The Ferguson System Principal An implement cutting through the soil at a certain depth say eight inches requires a certain force or draft to pull it. Obviously that draft will increase if the implement runs deeper than eight inches, and decrease if it runs shallower. Why not use that draft fact to control the depth of work automatically? The draft forces are
