Good Evening Keith, Well, if once the starter motor engages she cranks pretty well with no slow spots, I believe the problem may be in the push start switch or solenoid, or it could even be a bad cable connection somewhere. A weak battery or bad cable or grounds or solenoid connections can cause solenoids to chatter, so be sure the battery is well charged before you go through all that below. 1) The first thing I would try is to use a jumper wire to jump around that push button switch and see if she acts the same way. Similar, that could be accomplished by jumping a hot wire (12 volts) to the small terminal on the starter solenoid which accomplishes the same thing. You can also achieve that by utilizing the big post on the solenoids hot (not to starter) side terminal as the 12 v source and jumping it to the small solenoid coil terminal. These tests are to see if the push button is bad. If she works this way but not using the push switch, I would inspect and replace the push switch if bad, its the least expensive and first thing I would check. 2) If the push switch does not test as any problem, and she still acts the same way when its by passed, before testing the solenoid, I would remove, clean and wire brush, re attach and re tighten EVERY SINGLE starter and solenoid and ground and battery cable end. 3) If after cleaning and re tightening all above and she still dont improve, I then suspect the solenoid or possibly still the starter. If the battery is well charged and you have cleaned all battery terminal and grounds and solenoid and starter connections and she is no better BUT the starter turns well with no slow or dead spots, I would work with the solenoid first, as its less expensive than starter repair. Its possible with good heavy jumper cables to jump direct from the battery (non grounded terminal of course) direct to the starter or starter side of the solenoid and see how the starter acts. Take care and be ready to press down firm when you make that junmped connection, cuz theres a lot of current gonna flow and spark and DO NOT let a hot battery connection touch up against ground. Now, if jumping the starter direct makes her crank welll and no slow or dead spots, then the solenoid about has to be bad. HOWEVER, if the starter still has those dead or slow spots, then I finally suspect the starter needs some attention, possibly just needs brushes or commutator work. Do these thigns and post back the results. If the battery is okay (have them load tested, cuz they could cause your problem) and ALL starter and battery and solenoid and ground connections are okay, I suspect the solenoid first, then the push switch, then the starter itself.
