WD 45 starting

WD 45 would start with starter doing some humming so took starter off and had it rebuilt. Put starter back on. Does a great job of turning over engine, but tractor does not seem to have any fire. Has plenty of gas. What else should I check that would cause it to go from starting before the starter was rebuilt to not starting at all now?
 
Look where the battery cable connects to the starter switch. There should be a smaller wire that powers the rest of the electrical system. Be sure it is connected under the battery cable. Look for mouse chewed wiring, any loose or hanging wires. Could be just a coincidence that it lost spark.

If magneto, there is no connection to the electrical system, just a ground wire to kill the spark, be sure it is not grounded. The points may need setting or cleaning, I believe the gap is .015".

If battery ignition, look at the points. Be sure they are gaped at .020" and are in good condition. They may need cleaning, sometimes they will get a coating of corrosion that needs to be cleaned off. Some contact cleaner on a paper business card will usually work, or a fine file.

With the ignition on, you should be able to see a slight spark at the points when they open or are arced with a screwdriver. If no spark at the points, check for power to the ignition coil with a test light or volt meter. If no power to the coil, look at the ignition switch. A matter of tracing power back to the battery, see where the connection is broken.
