Hi. I have a 1920 cat 10 track tractor I'm restoring, and I'm having trouble getting the gas to the cylinders. It's at the carburetor, it's not getting into the intake. I checked the compression, and it's about 55 - 60 PSI, but I'm not sure what it's supposed to be. All cylinders are about the same. Does anyone know what the correct cylinder pressure should be? Any info would be greatly appreciated. Thanks. Manny

Check for leaks in the intake manifold, In some cases the inside will rot out, check the seal between the block and manifold. Have you tried priming through the Intake? It doesn't take a ton of compression to start on of these.
