I have a WD45 that quit running last week and refuses to start or even fire. It has been converted to 12 volt, I have spark from the coil to distributor. Could points be "burned". Also what are the "intial carb. settings. ? Thanks in advance.

The spark from the wire to the coil should be small. To determine if the distributor is working properly, pull a plug. Reconnecting the plug wire and grounding the plug, turn the engine over. If you get a nice spark on the plug, points and condensor are probably OK. If the spark is good, start looking for a fuel problem. If there isn't a spark, it could be the points or the coil. You said that the tractor had a 12 volt system. The coil was designed for 6 volts. If the conversion to 12 volt did not include a ceramic dropping resistor, 12 volts will cause premature failure of the coil - they over heat and burn up. Since you say it stopped suddenly, a bad coil is more likely than burned points - points usually cause hard starting before failure. Coils will go at operating temperature and will stop you dead. If you have a large spark between the wire and coil, this could indicate an internally shorted coil. Good luck,
