[Healeys] A bit of tuning advice

After having problems with the poor running of my BN4, I put an electronic
ignition in the distributer (which was also overhauled) and rebuilt the carbs
using a carb kit.  However, I still can't seem to get any power.

I am pretty certain that the timing is right (having checked it with a timing
gun), all the electric connections (plugs, cables, etc.) seem to be sound and
I cannot identify any specific problems with the carbs (ie leaks around the
inlet manifold, etc.).

So I think the trouble is with the setting of the carbs, but I have been up
and down the adjustment nuts (rich to lean and back again) without any

The symptoms are ... a smooth idle, smooth but very sluggish pick-up on
acceleration accompanied by a loud machine-gun type rat-ta-tat-tat!

Any ideas?
