Distributor with orange box

[darm]

The distributor on my 69 383 that comes with the mopar orange box does not advance when i test .
The vacuum module is holding a vacuum and that distributor should advance is that correct?
Thanks
Don

pull and plug the vacuum line off the dist. put a mighty vac on the dist and start the car. start to pull a vacuum and check your timing to see if it advances. you may have to make an adjustment of how much vacuum it will take to start moving the advance. you will also need to run a vacuum gauge on the car when cruising and accelerating to know what your car needs. if you need to make adjustments to the vacuum on the dist, you should be able to insert an allen wrench into the port. make small adjustments.

Thanks Mac
I forced it by hand yesterday and there's no way I could get that much vacuum from carb.
Since I have never owned a mopar I thought that might be common with that dist.
My problem is stalling or engine dies when flooring acellerator.
I replaced acellerator pump didn't help.

What carb are you running? My Edelbrock having 3 different accelerator pump positions. Is it possible yours has more than one and is not set correctly?

"Pump System:
When the throttle is opened rapidly, the air flow through
t
he engine will increase immediately. The fuel, since it is much heavier than
the air, will “lag” behind. This contributes to a temporary lean A/F condition.
Regardless of cause, a solution is to temporarily enrichen the A/F Ratio
by mechanically pumping a small quantity of fuel into the throat of the
c
arburetor (Figure 7). The Edelbrock carburetor has a piston that draws fuel
into the pump cavity past the plunger lip-seal when the throttle is closing
(1). Upon opening, the lip-seal seats, allowing the plunger to force the fuel
through another one-way valve, the Pump Discharge Ball and Weight (2),
and the Pump Jets (3) into the primary throats.
The pump plunger is not driven directly by the throttle, but through an
intermediate Pump Drive Spring (4) that extends the duration of the “pump
s
hot” past the time the throttle stops moving. The Edelbrock Performer
Series carburetor has an external pump lever with three hole locations
for link attachment providing three distinct pump delivery curves. This is
further explained in “Calibrating The Pump”."
