I think most people agree that the SVDA (Single vacuum dual advance?) dizzy is best for stock carbies.
Has the best response curve, because it uses both vacuum and mechanical advance.

i have a 1600 SP with a 009 dissy and it has a wackin great flat spot......if the engine is stock then stick with stock components they were made like that for a reason....i would never have put this 009 on my motor but the guy who had the car before me did it.

I have a 1600 single port with Solex Carby & Bosch 009 distributor and NO flat spot...
I did have a 1972 1500 Beetle with solex and 009 distributor & NO flat spot...
Have You timed the 009 at 32 degrees total advance... with the engine revving...
If the flat spot persists, You can adjust the accelerator pump slightly to pump more fuel when the accelerator is pressed...

It IS impossible for a 009 distributor to advance as quick as a stock vacuum/mechanical distributor... as it has to wait for the engine to rev before it can advance the ignition...
If You have a lightened flywheel, exhaust extractors etc...
You may be pleased with the 009... otherwise stick with what Volkswagenwerk knew...
