When I turn my ignition key the starter motor always goes;"er ...er... herrum" and the engine starts. Is this a sign of a starter motor problem? Just curious.

That is one way to describe it! If it is a mite hesitant but wasn't before maybe you are due for a new heavy duty battery.

One thing to try, and it’s free, is this fix by Gene:

It could also be ignition timing but Do the electrical stuff first.
If you do the wiring mod listed on Gene's site, be very careful to bend the cable ends and make them line up squarely on the stud (bolt) perfectly on the solenoid BEFORE tightening the nut. That bolt is copper and soft. I know of one person who broke it off trying to do that mod. If you do break if off, replace he entire solenoid rather than just the bolt. The back side of that bolt wears over time. There is a spring loaded round copper washer that touches it and the other bolt on the bottom during starting. It needs to hit the two contacts squarely. If one is worn and the other is not, then that will not happen.
