Although I sold the 69 Spitfire to my girlfriend, I still work on it.  The 
latest problem is starting.

The starter will engage initially quite well, and crank the engine 
around.  At some point the starter disengages, and makes that rrrrrooo sound.

The engine isn't even close to starting yet.  It takes her about 10-15 
cycles of this rr-rr-rr-rrrrroooo to get going.  Even when I do it, it 
takes me about 5 trys.  

When the engine is warm it starts right up so we don't get to the 
premature disengagement.

OK... I pulled the starter and examined its teeth.  They are quite shiny 
with severe scalloping toward the starter motor side.  Would this cause 
the disengagement, or is it a symptom of something else?  The starter in 
my parts box has wear in the same pattern, though slightly less severe.

The teeth are >not< shiny toward the opposite side from the motor.  
Doesn't look like they are taking a load there at all.

Remember, the starter always engages the first time (so I don't think it 
is a broken tooth on the ring gear) and cranks for many revs the first 
time (filling up the carb bowls after a long sit).  It never makes the 
scraping noise I associate with broken teeth.  It just gives up a touch 
too soon.

I'd like to put a new starter in, but don't want to wear it the same way 
as the last two if it's abnormal.

Thanks!
