TR3a distributor worn shaft?

["David Templeton" <davidt@opentext.com>]

Afternoon all,

 

I still wrestle with the pain in the a$$ idle, I believe it was Randall that
mentioned checking for the a worn dizzy shaft etc.  What does this entail
really?  Is it the top part of the dizzy that gets worn or is it the lower
drive part?  Can I test in car or components coming out and bench tested.  

 

I thought there felt like no play, but I better make sure.  Except for this
the '3 has huge power and run great, just can't idle.

 

Thanks in advance
