I ran y little Oliver HG dozer all week in the Michigan UP. Took out a lot of huge stumps and built some more road. Kind of amazing little machine. I will not though that the soil here is all sand and that made grubbing out big stumps a lot easier. This crawler has a lot more traction then power. I have a aux trans and if I ran it in the original lowest gear - the engine would stall when pushing on much of this stuff. I was in low-low with most.
I am still cursed with the hot-coil problem (as far as I can tell). I am on my 2nd magneto and third coil. I can run 3-4 hours steady before the magneto gets so hot, I loses spark. Once it cools, it runs good again. I assume theses things were tested when new and did not have the problem back in the day? Hard to figure. Only two new variables here I can think of. #1 is new aftermarket parts maybe not as durable as the original? #2 the exhaust manifold is closer to the magneto then it was when new. The original exhaust manifold on the Hercules engine swept up higher and had "Oliver" letters embossed on it. This has a Hercules replacement manifold that sits a lot lower. It came with a special Z-shaped carb adapter since the carb has to be mounted lower to make the manifold fit.
Funny things is - while in the woods, I came across this old IH on an adjacent 800 acres of hunting land. Looks like it was left there many years ago. To my surprise, I turned the crank and it is NOT stuck. Even still has compression. Has an IH distributor on it instead of a mag that just might fit my Hercules.
