The float height has a minor effect on the whole fuel curve.
Mixture screws are app 1 turn out, maybe 1 1/4. Yes they are responsive and will shut the car off when dialed too far in. Using a vacuum guage I'm showing a steady 15hg in drive at 650rpm.
By "too rich" I'm saying it makes your eyes water anywhere near the back of the car, and very very minor dark smoke at idle at the tailpipe.
Your Canadian, you know how some mornings its just cold enough to very lightly see your exhaust when the car is warming up, that's what its like.
Yes I nknow I need a wideband but can't make that happen until next month.
