Rick, From your earlier post, I thought you had already done a leak-down test. A leak down test is where you put compressed air into a cylinder via the spark plug hole. The fitting can be an old spark plug that has a pipe fitting brazed to it. It is connected to a gauge and shut off valve. The cylinder is pressurized, then the valve is shut off allowing it to be trapped and the pressure is monitored on by the pressure gauge. Some local auto parts supply stores have a fitting for the spark plug for leak down tests. Also, this same fitting is used to pressurize the chamber to replace valve springs without taking off the head. You may not be able to find a fitting, because the CASE G-148 uses an unusually large spark plug thread. If you are not getting very much compression, put some ( about 2 tablespoons) heavy weight oil (140 weight gear lube)in the spark plug hole and run a compression test again. If it is higher the rings are probably bad. I rebuilt my CASE G-148 about 2 years ago. It was an easy engine to work on. Do it right and get a complete kit with sleeves. Re-ringing with a taper in the cylinder wall won't last long. Mine is a CASE-O-MATIC. It's difficult to seal between the oil pan and torque tube. I had to do it twice to get it right. Also, the nose of the starter is in transmission fluid, so it had to be adequately gasketed. Good luck, Ken McWilliams Dayton, OH

Field Modifications (Sins of the Farmer) - by Staff. Picture a new Chevrolet driving down the street without it's grill, right fender and trunk lid. Imagine a crude hole made in the hood to accommodate a new taller air cleaner, the fender wells cut away to make way for larger tires, and half of a sliding glass door used to replace the windshield. Top that off with an old set of '36 Ford headlight shells bolted to the hood. Pretty unlikely for a car... but for a tractor, this is pretty normal. It seems that more often than not they a
