I've had a lot of magneto trouble the past year and am kind of fed up. This on my 70 year-old Cletrac crawler with a Hercules engine. Note - I use it pretty hard. To me, this is not a collector's machine. I have done a lot of work with it. Last spring - after being in storage all winter - it had no spark. As usual, the points oxidated and it is quite a project to get the mag off and clean them up. After that, a few weeks later it started losing spark after it got good and hot (took a few hours of pushing dirt). After it would cool off, it would run again until hot and then quit again. I figured it was the coil in the mag. It had the wrong mag on it anyway (Fairbanks Morse FMJ from an Allis Chalmers). So, I bought a brand new Wico XH since I was sick of jerking around with this thing and it is out in the middle of nowhere. The new mag worked great for a few weeks until winter came and I put it back in storage. Come this spring - no spark again. Yes, brand new mag and points got oxidized. So pulled this one all apart, cleaned them up, got it running. Used it for a few weeks and the coil went bad in the Wico now. So I just got a new coil for $70 and now it is running good (for now). Maybe the quality of parts are not what they used to be? I ran it five days straight building roads in the Michigan UP. Running great but I want to do something to make it more reliable. I am wondering if anyone has coverted a mag to breakerless? Seems if they do it on lawn-mower engines and chainsaws, there ought to be a way to do it on one of these self-contained mags. I do NOT want to "reinvent the wheel" though. Hoping to find someone who has already done it.

Today's Featured Article - Hydraulics - Cylinder Anatomy - by Curtis von Fange. Let’s make one more addition to our series on hydraulics. I’ve noticed a few questions in the comment section that could pertain to hydraulic cylinders so I thought we could take a short look at this real workhorse of the circuit. Cylinders are the reason for the hydraulic circuit. They take the fluid power delivered from the pump and magically change it into mechanical power. There are many types of cylinders that one might run across on a farm scenario. Each one could take a chapter in
