544 won't keep running and/or start

I need some pointers on this problem. The old tractor was always dependable. Starts right up, idles good and has always stayed running. This past week it sat on the auger filling trucks. Once again it would start right up. Maybe it might hesitate off and on ... not too much out of ordinary. Well, after running the auger for a half and hour or so it would just quit. It would not start again for 15 to 20 minutes. Then it would start and run OK. Now it won't start. You can crank and crank on it and it won't start. Always seemed to have good fuel flow at the sediment bulb, through the fuel pump and out of the carb. when the fuel bowl screw was opened. Any ideas??? I didn't know if the coil and points might start to act up when they get hot??? Thanks. andy
 
You need to check for fire to the plugs, pull off one of the plug wires and hold it near a good ground or 1/4" away from the plug while someone makes an attempt to start the tractor. No fire from plug wire check for battery voltage to the coil. Should have voltage on both terminals with points open and switch on. Clean the points with some 320 wet or dry. If they're pitted replace them and condenser. If you have a ballast resistor installed between the switch & coil it may be defective.

If there's fire to the plugs you probably have a fuel problem with dirt or rust in the gas tank or gas line. Remove the gas line at the carburetor and see if there's a full stream of gas. Hold a clean container to catch the gas. A trickle isn't enough. If there's a full stream of gas check for a screen behind that tube fitting for a screen. It could be plugged with crud. Be careful not to damage that fitting. Hal
 
Make sure the fuel tank vent is not clogged. Sounds like a condenser is acting up. If all the other advice doesn't help, swap in a different condenser & points.
