what's your back bleed/ex valve size.
If it stalls on initial throttle opening, the accel pump ckt.
is the culprit.
It's a combination of pump valve size, duration, and bleed back.
Close off the ex. valve (usually at like 40 or 50) let the fuel pump
shot go to the throats rather than some going back to the float bowl.
It's either that... or it's bogging because it's too Rich on the accel pump.

I'm trying to cure the off idle flat spot on my 62 Sprite. I yanked out my
40DCOE yesterday to check it out to go through it and see if I can make some
changes to cure this problem. I need to correct this as it's pretty much
undriveable in traffic. As soon as I dip into the throttle it stalls and
sometimes dies completely. I've tried to be as light as possible on the
throttle but it still does it. Any ideas as to which direction I should
take.
The carb particulars are:
Chokes: 32mm
Aux. venture: 4.5
Emulsion tube: F2
Main jet: 145
Idle jet: 45F9
Pump jet: 50
Starter jet: 85F9
Air Corrector: 175
This is a "stock" 1275. Don't know anything about the internals, the PO had
it rebuilt with what he assumed was to stock specs. It does have a header
and a Mallory Dual Point distributor.
