Gotta ask, why not just raise the jets a smidgen? 

Of course, everyone knows the sophisticated engine management software in Healeys only runs lean during emissions testing.

run down the highway at 60mph for 5-8 minutes. shut off engine and coast to the shoulder. Remove a couple plugs..say #1 and #6 and look to see if they are black/carboned up/ wet or are they dry/coffee w/cream color? Or find a shop with a gas analyzer who will check the exhaust gas at different rpm ranges.. I prefer the 1st way as the test is under normal loads...

Howdy all, 
I have HD 8 carbs on my BT 7 engine with +.40 pistons and a BJ8 cam grind. The car seems to run rich. I wanted to play with leaner needles and was wondering what ones to try?
