Sounds more like timing issue to me. Once it gets rolling the advance gets over far enough that you come near normal and it starts to run right. Have you done a timing check on it? Got the tools? You may just be able to loosen the IP for starters and see if you push it towards the head it picks up RPM and smooths out for now. Very tiny movements are all it takes. Mark a line across the IP and the bracket it is secured to so you can come back to that adjustment if moving the pump makes things worse.Best I can think of for someone with a new to them Rabbit and no manual or specific tools.
If you truly want an engine which cleanly grunts off the bottom and rips right to the top with minimal smoking, etc., then, put forth the effort to thoroughly port the intake and exhaust ports. Air in....air out....quicker rotation of the turbo vanes.....cleaner burning with all or almost all of the turbo lag gone. It certainly works well for me in multiple engines...and I live between 3500 and 5500 feet elevation here in the greatest country in the world.For me, running one of these NOT ported is like trying to win a 5-gallon bucket of liquid drinking contest, while using just a straw. Makes very little to no sense.The same principle works extremely well for my later ALH engines as well. I've got two stock alh Beetles which will quickly creep up to 100 mph on the open road if not careful.
On further test driving i noticed something else. I have poor throttle response for the first 2\3´s of the pedal. Can this have something to do with the max fuel screw? or where should i start looking?it is like at 2\3's pedal i'm only getting 30% power and from there on is a sharp increase in power. (so full pedal is 100% power).Sort of feels like its only running on 3 cylinders up to 2\3's pedal then on all 4 from there on.Throttle linkage is working properly full pedal opens the pump all the way.i am aware the pump hasn't been runned for at least a good 3 years. i do plan on running a good lubricating and cleaning additive as soon as i fill the tank.maybe it just needs a good running in?...thanks!

I've noticed I have to move my foot more either way to get the same response if the screw is out too far. Try threading it in a half turn and then thread the full throttle limit screw in a little. The go pedal won't depress as far so you can adjust the stop under the pedal to save the cable.
