[Mgs] Pertronix and overheating in MGA

[W. David Houser]

Listers,
The Pertronix instructions infer that the ignition timing should be  
reset after installation of the Ignitor. This was not done, as the  
sales pitch is that the Ignitor is a direct (and immediately  
reversible) replacement, and it is not obvious how replacing points  
can advance the ignition. The  engine is not pinging, but it does idle  
faster, and there is now an overheating tendency on warmer days. Does  
anyone have any experience with the Ignitor in this regard? The car is  
a 1600 MGA 1960.
TIA
