Technical Weber 32/36 on 53 235

So my 53 has Langdons 32/36 carb upgrade. It has sat for a bit with fuel in it. The other day if I apply the throttle quickly it’ll wanna die as if running out of fuel. However if slowly applying throttle, it accelerates pretty good. So I have replaced the diaphragm for accelerator pump.
Still issue persists, starts up and idles perfect just the instant of applying throttle quickly it’ll sputter.
My Dad comes over to tinker with the carb and pointed my choke is fully opened. I assumed once it warmed up it should be fully open. Although my dad just applied little pressure on choke plate, just a hair, tested the throttle and it was perfect no hesitation. Messing with the Choke side piece, rotating the choke don’t seem to make any changes. It’s warmed up and it won’t move. We attempted with the electrical connector disconnected and connected as well.
Looking through few PDFs file can’t seem to find ways to adjust the plate. When I accelerate my distributor does rotate, my point have been upgraded to Pertronix. I have an electric fuel pump.

 

Do you see a squirt from the accelerator pump nozzle

 

I do see squirting

 

There should be no gap in any of the linkage between the throttle shaft and the accelerator pump diaphragm, and the fuel should start to come out of the squirter with the slightest movement of the throttle.

Here's a bit longer procedure for general setting up of the Weber:

I have fuel squirting throughout the whole throttle application. New accelerator pump installed.

 

Have you checked for a vacuum leak?

 

No leaks found using carb cleaner
