Run-on Problems

[Longstreth24@aol.com]

Just bought a '62 MGA Mk II and I'm having some trouble with run-on after 
turning off the ignition switch.  I've played with the carbs (tried running 
richer) and have adjusted the timing, but I'm having no luck.  

A read that chamfering the tops of the cylinders might help prevent this, but 
that sure sounds extreme.

The engine is a 1622cc block with an MGB (1800cc) head.  It's got the 
standard dual S.U. carbs (a little leaky).  Any advice certainly would be 
appreciated.
