Hi matey,
to scuk
Do you know what piston spring is in your SU? Most people find that a yellow one works best on the 1600 ( the tips should be coloured) if its got the wrong spring the piston rises at the wrong speed and give the wrong air:fuel ratio.

I had all sorts of annoying problems before I put the yellow spring in... 25-75% throttle was a flat spot
