1972 Float Adjustment ...

well it does start but it takes a lot of gas pedal to start. Anyway i cleaned all the plugs with a brass brush before cranking it and drove it slowly with the choke on for 10 minutes. Aceleration is still rough. It misfires a lot and now even with both idle screws at 3,70 turns clockwise whenever you accelerate you can hear the car backfire through the carbs. Major disapointment. I measured the fuel pressure and its still at 3 psi. 

Once i returned home, i sprayed carb cleaner to the carbs and intake manifold and did not notice any vacuum leaks. There is something not clear here.

@jalexquijanoI think a new set of plugs is a good idea. Let's remove those from the equation. The old ones may be screwing with the results of your tests.

Why??? I have already cleaned the carbon deposits with a brass brush and still when driving the car the idle is rough.

 You'll find out WHY when you change them.

How much will you gap them? .31 or .35 or is this irrelevant?

What was the gap on the currently installed plugs?

.32 from stock

Good grief. I thought this carb issue was solved already.

Anyway, if I remember, you were running a Pertronix ignition setup.

Use their gap. not stock gap.

You can not clean gas fouled plugs. @jalexquijano

Just got 2 sets of Ngk bp6es. I will also check pertronix ignitor module air gap and will verify the plugs gaps.

Should he really even need to use the cold start (choke) in Panama?? I live in Chicago and never need it even in winter

Then there is a problem that my mechanic has not been able to identify.
