I agree, based on the limited input, you have a bad connection at the battery or one at least one end of the major cable to the starter or to the engine/chassis ground.
As cowboy303 says, tie-wrap your FSS into the up position for pull starting.
The easy way to determine where the high resistance is in the cable:
hook up a voltmeter, positive on the battery, negative on the starter large post, monitor it while cranking. It should read less than half a volt.
Then hook up negative lead to battery, touch positive lead to clean metal on the starter housing, and monitor while attempting to crank. Again it should read less than half a volt.
The high resistance connection, especially if it is a cable lug, will often get very hot when cranking.
More details are in the "starting" section of the free factory service manual that you can download at the top of this forum.
