A very wise man once told me that "most carburetor problems are electrical". Another told me "Start with the easy stuff first". Does it seem to get hot? First thing I would do is remove the high speed needle from the carb. and check the tip to make sure it's not bent, probably most importantly check the little holes in the sides of it's shaft, get a tiny piece of wire and clean them out, try to run the wire up through the inside of the needle through the holes in the side, then blow it out really good, then make SURE that air can easily go in one set of holes and come out the other, while you are looking at the carb check the throttle shaft for wear if the shaft hole is worn you will never get it run right, it will seem like one thing is wrong one time and something else the next. Check the coil and make sure that it is a 12 volt coil with an internal resistor. If a coil reads "12 VOLTS" on its casing, then it has a built-in resistor, if it doesn't say "12 volts" then it probably isn't, and should either be replaced or have a ballast resistor installed, to prevent it from putting too much voltage through the primary circuit and ignition points. Then I would try to set the points with a timing light, it is possible that the cam is worn where the push rod for the points is, or the rod itself could be worn, and if you haven't already, replace the condenser. If none of these things seem to work for you then go here, http://gardentractorpullingtips.com/ignition.htm and read what this guy says, you'll be glad you did.
