[Healeys] air/fuel mixture

[Greg Lemon]

I agree with Alan, when I had my Hundred I rebuilt the carbs when I first 
got the car, then about 8 years later rebuilt the motor, I needed to rebuild 
the carbs again to get it tuned right, as they ran rich (I had not replaced 
the needles and jets on the first rebuild).

That being said the running rough and overheating could be caused by timing 
being off, would check that before I started tearing things apart, good 
luck.
