My 74 MGB Won't start Correctly it's Weird!!!

Hello,

   My name is Oren Persons I own a 1974 MGB Roadster that doesn't seem to be 
starting the right way these days.  The symptom is simple when I turn the key 
to get it to start it the starter motor keeps turning and the car keeps 
getting gas every thing seems normal but it won't turn over.  As soon as you 
let go of the key from trying to start it she fires right over?  I don't 
understand it.  Any help would be appreciated.   E mail me at 
OHPNINMG@aol.com.  I'm on my labtop at college.  Thank You very much
