excluding a flat battery theres only 3 things that routinely go wrong with the 2.25 starting system

the solenoid

the startermotor main power post and brushes

earth connections.

IME about half the time its the solenoid especially when the customer comes in with any line that leads along the line of "well its been getting slower and slower to crank and takes longer and longer to start"

Actually, you've missed the most common problem (possibly because it does not apply in this case) - bendix gear sticking, usually due to someone putting oil or grease on it, but sometimes just rusty. Not common, but I have struck the end bush chopped out allowing the motor to pole.

I've also had them spit the C clip, bendix come off and get wedged in ring gear.
I'm sure some one will think of more.

This happened to me. It presented as being very sluggish to turn over and start. I thought a flat battery, as the lights would also dim. Upon inspection, the starter cables were getting hot, which indicates a large current drain. This told me the the battery was good, as it could supply large quantities of current. So it had to be the starter motor polling out.

When the starter motor was polling out, it was effectively a short circuit (an electric motor not turning is electrically a short circuit).
