JC, Ray may have a point about the governor. While the engine is running at idle, grasp the linkage going to from the governor to carburetor and speed up the engine. As the engine speeds up, the governor will try to slow the engine and begin pushing against you to close the carburetor butterfly. If this seems to be OK, then another possibility exists. If you have a Marvel Schebler carburetor, they often have a screen just inside the elbow fitting where your fuel line connects to the carburetor. Many people don't know that the screen is there including me until I had some problems. I had an old Ford 8N that would run normal and sometimes would run up to 30 minutes, then it would begin acting up. The engine would lose power and nearly shut down or would completely shut down. The engine would restart immediately and run a few seconds to a few minutes perfectly and then stop. What would happed was that the fuel would run into the fuel bowl when the engine stopped and then use it up when the engine was restarted. If you remove the gas line it should flow about a pint to quart per minute. If not, fix what's up stream to the tank. Remove the carburetor's bowl and check for fuel flow again through the carburetor's fittings and float valve. If still about a pint to quart per minute, then we need to look somewhere else. If the fuel runs slow, then inspect that screen attached to the fitting and blow it out with an air hose and reinstall it. Good Luck! Ken McWilliams
