Ok so motor was running, slightly high idling speed. Drove okish. Very sluggish throttle response. Problem i am now facing is that it idles fine, but the moment ypu push the accelerator, she dies. I literaly have to pump the accelerator aggressively for her not to die, but she has no power and wants to die when in gear. I did notice what seems to be like a black soot on the carb and also on the carb intake. Any advice?
Is the soot oily or dry? If its oily, you must have had a back-fire through the carb.
As stated above, have a look down the carb throat to see if the accelerator pump is doing its job. If you pull back on the go-faster cable, there should be a nice strong stream of fuel coming out of a faucet looking pipe. If it delivers a nice strong even squirt, make sure the squirt falls directly down the carb throat and not one of the walls.
If you need to clean the carb, or rebuild it, here is a lekker video which explains the process step by step:

Make sure you have adjusted your carb properly. But to do this, you need to make sure your VW is properly tuned. See the tuning procedure:

If you do the above, 99,999% of the time it will resolve your issue. The tune up procedure will take some time, but if you approach it methodically, you will not only learn the intricacies of your aircooled motor, but it will help in future to eliminate other causes.
My engine did the same as yours and after fiddling for a few hours (did not follow the tune-up procedure) my issue was as simple as an airleak in the intake.
May the aircooled gods be with you
