Wow its been a bit of a bugger this scoot, but I've finally got all systems go.
It turns out that i had two problems:
One was the carb
The second was the dc cdi box
I'm still a bit unsure of what was going on with the carb, but i did notice some differences between the old carb and the one i got off the wreckers. Firstly the build quality was way better, i think my old carb was built on a Friday afternoon just b4 Chinese new year, shiit. Slight stepped wear on the needle slide, needle slightly loose in holder, cracks in metal, made from less metal even though same model (maybe an upgrade?), anyway once i replaced the carb, engine did not die out like b4, but it didnt run smooth either, couldnt hold revs.
