Which distributor would you buy?

I have a balanced stock 1600 dp with a German 34pict.
I was running a svda that I had in my parts stash, but it would never
Maintain proper timing. It would stay advanced as much as 20 degrees at idle.
I put a 009 in for now, just to keep the timing more solid and it works.... And doesn't even have the 009 flat spot.
But I can tell that it doesn't run to its full potential. I want to get a new distributor. Should I just get a new svda? Or is there something comparable or perhaps better?

010 is always a nice choice

If you're sure that your 34-3 is working well, I would stick with a good SVDA. Make sure that your 34-3 wasn't originally designed to work for a DVDA; those have different idle settings.
That being said, I have ditched both of my 34-3 / SVDA combos for a properly jetted H30/31 and 010. I get better overall performance and the H30/31s are less finicky than the 34-3s.

Personal experiences may vary.

Yeah, I ran the #s on the carb base and have the proper jetting for use of the svda. I did replace the throttle plate with another that has a smaller hole in it ( the one that some suggest to seal up when using an 009)

My old svda I could rotate the rotor through it mechanical advance range and it would stick wherever you put it.

Wish I could get the 010, but they seem a little to spendy for me right now.... May just have to try another svda.

Funny, years ago.... I worked in a dub shop and we had boxes upon boxes of old cast iron distributors. Wish I knew what I know now!

I have found two 010s for cheap at a local VW scrap yard. Lucky, I guess. Trouble is, all the tune up parts for them are getting pricier by the minute.

Thanks Glenn.... I'll put that on my wish list. I was digging around in my parts and I have 3 of them... You'd think I could get one to work as good as my ole stand by 009. I just got back from driving it,and it runs pretty smooth, even at a third gear lug... Pulls right out of it with ease. So I'm anxious to see how a good 034 will do!

Would an SVDA also be better than the stock DVDA with a 34-3 on a bone stock 1600?
My dual vacuum is ready for a rebuild, but if the SVDA would perform better, I'll go that route.

so what is the issue with the 09?if it dosent have a flat spot whats it not doing?why dosent it have a flat spot? does the car feal like it has a strong power band down low that comes on?? thats usualy the flat spot it is getting over.some cars stumble some have a peaky fealing, some just lay there then start comming on. I love my 09's when there fixed.

First of all what was causing the distributor to stick in advanced? Can that be resolved? (i.e. Do you have a broken spring? Have you connected the vacuum advance to manifold vacuum instead of the carburetor advance port? Is the high idle cam or a sticky throttle cable possibly opening the throttle plate enough to advance the distributor?)

Second of all, what are the advance curves for your engine? If it is "stock" than what came with "stock"? Wouldn't that be the distributor to most likely have the advance curves that would be optimal for your engine? If you really want to get a distributor that follows your engine precisely then wouldn't getting your engine dyno-ed and then adjusting the springs, weights and tabs be the best rather than blindly guessing what distributor might have the best curve(s) for your engine?

Third of all what would you like your distributor to adjust for? RPMs only like a 009 or 010 or 019 would? Or would you like it to adjust for not only changes in RPM but also for changes in LOAD for better efficiency like an SVDA or DVDA would? Do you want it to retard back for better engine braking and emisions while your dashpot or idle adjuster is still closing like a DVDA would? Do you want it to stay retarded at idle for emissions by using the ported vacuum off the carburetor that shuts off manifold vacuum during idle? Or do you want to idle cooler and forget the emissions by running strait off of manifold vacuum? Do you want a greater voltage coil and balast so you could open your spark gap wider for better ignition during starting and with leaner fuel mixtures as is possible with electronic ignition? Or do you want to go all out and have an ignition system that adjusts for RPM, LOAD, TEMP, KNOCK, BOOST, etc like a digital system would?
