Stop in for a cup of coffee

That starter sounds like it is wanting a better ground to me, or the battery is low, or could the starter be pulling all the bolts because its wore out ? Just thinking out loud
Battery is probably a bit low, its been sitting a couple months. I put it on the charger over night.

So I'll start by checking the ground strap and the ohms
then move to checking/swapping the coil/dizzy.
