Hiya matt,
OEM vacuum or SVDA if you cannot locate an OEM vacuum.

Vacuum, without a doubt.
123 with vacuum if you're feeling flush: http://www.sciperformance.co.uk/onlineshopproducts_53353/prod_49227-123VWRV.html

Ive tried both and found vacuum advance a much nicer drive. No need to rev before pulling away to stop engine bogging down, nice smooth advance on vacs.
On a singleport, you don't really want the SVDA that heritage sell. You need the correct vacuum-only distributor for your engine/carb setup.
According to this:
http://www.type2.com/~keen/ignition.html#B6970" onclick="window.open(this.href);return false;
You want...
VW 113-905-205M OR 113-905-205T - these are vacuum only distributors.
SVDA stands for single vacuum, dual advance (as it has a mechanical advance element too, like a 009 but with vacuum advance too), and these were only fitted to twinport engines as far as I know.
I'd say your best bet is to pick up a used distributor from a VW show and clean it up, checking the play on the shaft and the cam lobes are all OK.

Hiya Tofufi,
I cannot speak to the SVDA that is sold by Heritage.
Over on this side of the pond aircooled.net sells an SVDA that is aces with a singleport. I ran the original 205T (a fresh rebuilt unit) and then I ran this SVDA. The performance was much better with the SVDA. And so, that is what I run now on my 1600 singleport. It was asked in another post if the choice of carburetors was important. In regards to this SVDA it is very important because differing carburetors have differing vacuum signals. The SVDA I use, for example is keyed into the 30/31.
Aircooled.net claims that users should see better performance (I have), cooler running (this engine is quite cool), and better gas mileage (I really did not keep track of my mileage before so I have no basis for comparison). I'm a very happy SVDA user.

Eek :shock:
Just bought an SVDA for my singleport as I'm fed up with the 'bogging down' that the 009 does. Hope to get it fitted next week as I've got nothing to loose as its paid for. Didn't realise the singleport needed just vacuum.
Heres some usefull info:

I cannot be 100% sure, but I do know that the SVDA were not originally fitted to the SP engines. I think the vacuum given is related to both the carb and the inlet manifold, including the single/twinport head differences.
I thought that the Aircooled.net ones had a modified advance curve for SP engines?
Hence, they have different ones for different carbs. Over here, we don't get that

Try it and see, it might be OK
I don't think they were ever fitted as 'standard' by VW though... Just check that the advance isn't going too high. It may be OK - personally, I'd be buying and rebuilding a secondhand one rather than buying a brand new one, at least to start with.
If the advance is OK, and it runs OK, I don't see any harm in using it. I ran a 1300TP (in my bug) with a vacuum only distributor (should have been vac/mech) for a while, and it seemed OK - but I was advised against it as the vacuum signals are different.

Just make sure when timing any dissy that the advance is no more than 32Degs.

With the vac hose plugged
On a stock SVDA distributor, with the vac hose connected, it can safely be as much as 40 degrees max

See the problem i've got is i know it's a vacuum. But the engine was put in with all the bits when it came over from the US. So dont really know if it is the original 68 only vacuum. What would you all recommend doing? shall i try stripping it down? and replacing a few bits...i.e cap, arm stuff like that???? Help
