[DeTomaso] Starter

[Asa Jay Laughton]

 Boyd,

Part of the problem is simply too much heat.  This is why starter 
shields are made to keep exhaust header heat away.  If you think about 
it, the start gets hot, and the simple rules of thermal expansion, and 
different rates for different materials, means parts of the starter are 
now expanded differently causing mild binding, like in the bearings or 
the armature versus the housing.  This is a common problem and seems to 
get worse with age.  Although it can be experienced with a brand new 
starter as well.  In this case, it usually means your timing is a tad 
too advanced so when warm the engine is fighting the starter.

I ordered one of the starters we've been talking about and plan to run 
it for a while to see if there is a difference.  Though I have to admit 
I am not currently having any problems with the stock style.
