If I would let my 88 F250 (302) warm up to normal tempatures then shut her down then try and restart, the engine would be sluggish turning. Then all of a sudden the engine would spin fast and start. It almost sounds like a low or bad battery so I replaced it with a brand new "Sears Gold" and it still does the same.

Is there a way I could take this starter off and have tested at a local auto parts store or is there something I could look at?

Any help would be great! Thanks for your time in advance.
