[TR] New Distributor for TR 2-4 ? Rebuild Rocker Assembly ?

[Jack W. Drews]

Often, but not always, what hapens to cause extra noise is that the 
contact patch between the valve stem and the rocker arm wears and the 
area outside the contact patch does not wear. I've seen older rockers 
with about a .010 groove worn in them. of course when that has 
happened, the feeler gauge doesn't feel the right things.
