Weber Tuning help..., my webers need some love Options

[Aaron Cox]

Ok, little background before you can help.

44 idf's - freshly rebuilt.
34mm venturi's
50 Idles
135 Mains
195 Airs
F11 Emul
Accel pump jets are 50 i believe (new style weber with non roller cam pump - adjustable)

Motor -
2L (71 x 94) 8.3: 1ish... Mallory unilite (12 deg/29 deg) CDI box, coil, etc (it aint foulin plugs with this setup.....)

CB performance TALL manifolds, and linkage.....


OK... so here is whatsup.

Idles great, played with mixture screws etc and went thru the pre-tuning procedure as listed in Bob Tomlinsons weber IDF book....

Air bleeds are .5 turns open and all barrels are flowing about the same. Idle mixture screws are i think 2.5 turns out... and thjose are the settings.

So the idle circuit seems to work OK. decent low end, Top end FLIES! but the transition is HORRIBLE. it falls flat on its face and sputters and then takes off like a rocket at WOT ( lean stumble? )

any one have any jetting suggestions for the above specs that may fix my stumle?

I have some 32 vents i can try, but have a feeling it will take away some top end....(might be OK if i pick up some more low end)

tired of fighting with them...

today, car felt shitty. it was backfiring etc... hasnt done that in a while. i am gonna change intake manifold gaskets, and see if i have an airleak...

any ideas???
