Re: Distributor Drive & Pinch Bolt

In the past I have seen the following causes for your problem:

1.  Someone overtightened the clamp and crushed the body of the distributor 
which can no longer offer resistance to the clamp sufficient to hold it in 
place.

2.  The clamp bolt is stripped.

3.  The clamp is cracked.  As you tighten the bolt you just enlarge the crack 
and you don't put any presure on the dist. body.
