It sound s like you have more than one problem. If you need a jump to get it started, then your battery is either bad or the charging system isn"t working. You"ll need to fix this first. When you get that fixed, then you"ll need to check the spark. Pull the center wire out of the distributor cap and gold about 3/16" from a good ground and try to start the engine. YOU SHOULD SEE A FAT, BLUISH-WHITE SPARK. if the spark is stringy and yellowish, redish blue, or even bluish, that"s not good. Gotta" be FAT & BLUISH-WHITE! iIf it"s not then you need to check out the primary ignition circuit. it runs from the battery, through the key switch to the coil and to the distributor points and to ground. Dirty corroded orloose connections can cause a problem. High resistance in the key switch can cause a problem. The coil maybe bad, the points may be burned, pitted or corroded or improperly set. The timing and the firing oreder(1-3-4-2) must be correct. With a 6 V system, everything must be working correctly to get a hot spark. If the ignition system is OK, Then go to the fuel system.Turn the tank valve full open and holding a suitable container under the carb, remove the big plug at the bottom. the fuels should CONTINUOUSLY GUSH OUT FOR AS LONG AS THERE IS FUEL IN THE TANK like a cow peein" on a flat rock. If it doesn"t then there is a problem with the fuel delivery. Check the "secret filter" in the fuel line elbow connection at the carb., check the fuel filter in the sediment bowl housing and if it"s not any of these, the inlet to the sediment bowl in the tank may be clogged. Also make sure that the vent hole in the fuel cap is not plugged. Finally, rap the side of the carb with a wooden plock to see if the float is hanging up. if these aren"t the problemthen the float valve in the carb is blocked and the carb has to come off for that. Do these checks systematically, one at a time,in the order that I wrote them and check and see if the change you made fixed the problem. Record your findings in writing so you can analyze them. What ever you do DO NOT WILLY NILLY START CHANGING OUT PARTS! Systematically check evry item out and you"ll find the problem.
if you don"t have a Ferguson Shop Manual, you really should get one. They"re about $20 and they have good sytem descriptions to explain how things work and how to fix them. It"ll pay for it self the first repair you do your self.
