you have the vacuum wrong to the Vacuum advance. (there are 2 types, of porting, hard plenum vacuum and ported above TV valve, )
when you start the engine i bet the vacuum advance comes on fact.
correct, cam is 1/2 crank , exactly 2:1 ratio, correct.
5 crank is 2.5cam degrees.
what direction is the rotor spin,? CCW (like our G16b?)
there were 2 vacuum nipples on the G16 vac, advance, does the G13 have 1 or 2,nipples.
and where do they go, your photos show no hose routings.
the 2 nipple system
the inside nipple is retard
the outside nipple is advance side , to prove that use a hand tool, out side nipple pulls rod inward, for advance) above inside nipple pushes other way.

no photos of G13 vac, adv. pot. if the nipple is on the rear of the vac. advance, then that is for sure an advance nipple.
this outside nipple must not ever be connected to plenum vacuum , if you do , the advance goes to max as soon as engine starts.
that be very wrong,
that the rear nipple does is add advance as you open the TV>
this is what is called, ported TV vacuum at idle it has , zero vacuum.
the old carb is gone i bet, and so we can not examine this feature, close, but it was there.
if you had a real FSM on this car, (book) it have advance data. there, tables. showing the ported vacuum rules,
have you examined the weber for this other vacuum port.
usually its a hard vacuum nipple down low, way below the TV . this is wrong vac.
then at the edge of the TV,
here is a 1 barrel carb,
see the gold TV, and see that tiny hole, this is vacuum advance port.
0v vacuum at idle, then increases as you apply throttle. this port advances the spark.
the location on the original carb perfectly matches a specific vac adv. pot, and its diaphram diameter,
here are 2 examples of how this works (advance, not smog retard feature , now missing)
see this port, this is downside, plenum side.

and this, this left gauge is ported advance, and this TV gated vacuum gives the engine, that surge of power off the line,..... (0 mph , and first right foot actions)
graphic, P = plenum, M = max vac, 0 = zero vac.

on the web, do not confuse idle fuel ports, for vacuum ports.
that weber has more identification letters, like DGV , DGEV ,DGAV and DGEV, and DGES. (elect, water or manual choke version)
there is a book on each and will show which port is which,
which weber is this? 32/36 is series,(and venturi size)
some have 2 nipples on body, below electric, chock pot.
left is egr, and right is dizzy.
but i always look at the port action with eyes, and blow in to ports to see what they REALLY do.
keep in mind , i have no e59, FSM , so cant say what suzuki was doing there.
on most engines of this class
but
when you accelerate off the idle, stops...
mech, advance, is pretty dead. (rpm low)
so what happens is carb goes way rich (by design and tune)"enrich mode"
this means you need more advance to burn the richer fuel, if this does not happen , you lose lots of power, off the line.....
then as speed builds, the mech advance kicks in and the VAC drops and the vacuum advance , backs off.
what i do ?
is i examine that old carb and see how the advance port works.
then on the new carb, make sure its the same, (forget the retard hose)
its that simple but, with the wrong carb and all is lost.
i dont have an xray drawing of the 32/36 carb, this would greatly help, and the manuals so far ive seen , lack this critical facts.(webers)
ill keep looking when you tell me the Dxxx letters.
