[Fot] TR3/4 starter issue

[Greg And Alison Blake]

Jack,

I had a similar starter issue back when the 3 was a street car it had the symptoms that you describe. It was an internal fault in the starter. From what I remember there was a bushing that had degraded over time that was causing the starter to not engage. It was spin just fine but could not engage an turn the motor over. 

Sorry, can't answer the other questions.

Restarting always catches, although sometimes this could take a few tries.  I’ve always thought this was the starter needed an overhaul, but have not taken the time to pull it and see.  The starter pinion and ring gear never crunch.  It either engages well or not, although it may engage and “slip out” occasionally.  This non-engagement gets worse with decreasing temperature.  On a 40 degree day, I have tried over 15 starts before it’ll catch.  This is unacceptable.
