When I come to a junction and try to accelerate the engine will not rev. up, I have to put it out of gear and rev until it picks up before I can drive off. I have changed the carb, cleaned it out and all the jets. The engine revs ok when stationary. What might be the problem?Please help me. Thanks in advance.

What engine?
Air filter all clean, plugs clean/ gapped, fuel filters clean, all vacuum pipes secure, accelerator pump working as it should?

It's a 1600 air-cooled. I set plugs to 025" All vacuum pipes are ok. The only thing I haven't changed is the pump diaphragm because I can't get one. No kit supplies the correct one. The diaphragm is about 40mm square. I have tried nearly all VW suppliers, but no luck. The engine revs ok when van is stationary and you can see fuel being sprayed into venturi. Air filter is new. The carb is a Pict 34/3. Thanks for your help.
