[Healeys] petronix

[healeymanjim at hansencc.net (healeymanjim at hansencc.net)]

want to help a guy in our club with a morgan that has a "missing and 
sputtering" problem.  he has a petronix in it and i know nothing about these 
things.  what should i be looking for.  suspected a coil and had it replaced, 
but did not solve problem.   will naturally check carbs, etc., but suspect 
ignition as car apparently starts and runs ok until it warms up.  any help 
appreciated as i will be "flying blind" here.
