Also, your car most likely has a relay above the steering column that links the ignition switch to the starter, as most later cars do. It might not be a 'relay' exactly, and more of a safety interlock of some sort. But, it can go bad and deliver weak power to starter. When mine went bad, the starter just made clunky noises, but yours may be different. New starter didn't fix problem, of course. The relay isn't available, but you can just bypass it by putting a jumper in. Figure out which post gets 12V when key is switched to starter position, and figure out which posts makes starter spin. Then just stick a wire between the two and wrap some tape around it.
Earlier cars did just fine without a starter relay, so it should be fine.
If you want to test if your starter is really bad, and not just ignition switch or circuit, just jump 12V from your battery straight to the switched post on your starter. You can even do this by just laying a screwdriver across the posts just right (it will spark, a lot). If giving 12V straight to starter makes it spin fast like normal, then you'll want to be looking elsewhere.
Your 200ner may already bypass the relay though with its starter button, not sure, and not sure what other weak connections it may go through though. .
