[Mgs] MGA Points

[Robert J. Guinness]

I have had to replace the points on my MGA's distributor after only 3 
months of service (less than a 1,000 miles).  Apparently, the rubbing 
block wore down so that the points remained closed.  The points could 
not be adjusted to increase the gap because they were already fully 
adjusted out.  I used Lucas points, part #151-720.  Has anyone else 
experienced this problem?  Is there a cause other than a defective 
part?  If so, what should I do to prevent its reoccurence?  The 
replacement set that was installed is also a Lucas 151-720.  When I 
installed the new set, they are adjusted nearly all the way out (i.e. no 
more room to open the gap much further).  The problem surfaces when it 
gets progressively more difficult to start the car.  However, once it 
starts, it runs fine  --  until the next time when it won't start.
