I need advice and some help on what distributors play well with what carbs on a 1600DP engine. Preferably with the Solex 30 Pict 2 if possible.

I've got a 1600DP in my 67 beetle and I'm wanting to go with a pointless electronic ignition. I have a dual port intake manifold with a single port flange welded to the top of it.

I know it sounds like a really weird setup, but when it used to run, it ran so dang well! It seemed to have a little more bottom end torque than other bugs I've driven that had a standard 1600DP setup. I really enjoyed it a lot, and I miss having it running.

My ultimate goal is to just get it back to where it was when it ran the best. It was running with a 113-905-205M distributor, and a Solex 30 Pict 2 carb. I'm hoping I can achieve the same result of the 113-905-205M, but with an electronic pointless ignition because these modern day points and condensers just don't last any time now.

I was looking into the Pertronix SVDA style units, and I was also looking into the Empi units as well. The reason I'm here asking advice is because the website I was on looking at the Empi ( either Jbugs, or Cip1, I can't remember ) clearly stated the the Empi SVDA style unit does not work well with the 30mm carbs, and to use them with the 34mm instead.

So, what do you guys think? Are there any pointless electronic distributors that work well with the 30 Pict 2?
Or would I be better off just scrapping the old intake manifold with that single port flange and go to a normal dual port manifold with a 34mm carb with a pointless distributor?

If the answer is to go with the proper intake and the 34mm carb, which distributor will work best, the SVDA style or the 009 style?


Thanks!

The 30PICT-2 doesn't have a compatible vacuum signal to work correctly with an SVDA.

If you still have your 30PICT-2 and 113-905-205M distributor pairing that worked so well, just get a drop in points replacement module.

Right on, I didn't know that the 30 Pict 2 didn't have a compatible vacuum to work with an SVDA. This is the only VW I've ever had, and I'm still learning all these weird things. I wonder why it ran so well then? My bug is definitely a special snowflake! Lol

Would a 009 style unit work well with the 30 Pict 2?
Also is there any drop in points replacement models you would recommend if I decide to keep that 113-905-205M distributor?

Thank you for your help! I'm really wanting to get my bug back on action.

If you're running a dual port engine in your 67 bug, you're best option is a rebuilt/restored German Solex 34-3 carb matched to a restored German Bosch SVDA distributor.

The original 67 engines were single ports with a 30-1 carb matched to a 113905205K SVA distributor. The 205M is a 1968 distributor but would also work perfectly with the 30 series carbs.

The Pertronix distributors are poorly made Chinese copies of the famous Bosch 034 distributor. I've autopsied a couple and they are made with poor materials and terrible tolerances. After the autopsy, the parts were pitched into a recycle can.

The points replacement modules are a hot topic. Some people have luck with them while others won't run them due to them not being as reliable as the old points and condensers.

Our old VW's start, run and drive best with the original restored parts that were designed for them. The carb, distributor and fuel pumps need to match for the combo to work correctly.

Thank you wcfvw69 !!
So, I wasn't crazy, the 30 pict 2 does work with an SVDA distributor. I thought it ran pretty dang good back when it was running at its peak.

What's the difference between the 205M and the 205K distributors? I'm getting a rebuilt 30 Pict 2 from Volkz bits, and I was toying with the idea of also getting a rebuilt 113-905-205M distributor from Sparkxwerks. ( I think that's you. Lol ) The idea being that's what it had on it when it ran good, so I should just go back with known good parts.

The whole reason I was leaning so heavily towards an electronic ignition is because I really thought they were supposed to be much better quality. From what I've been seeing lately, the points and condensers that are available now for rebuilding our old stuff is just terrible. The plastic rub blocks on the points wear out within a couple hundred miles, and condensers that most of the time don't work at all. I was really hoping that the electronic ignition systems would offer better long term reliability. That's the pipe dream anyway.

I know that if I get a rebuilt 113-905-205M, it will last a while, but my concern is that I'm going to have to replace the points and condenser eventually, and the parts that will be available when that time comes just won't work and I'll be right back where I started. I was just trying to find what's going to be the most reliable over the longest term.

Your 30PICT-2 works well with the 113-905-205M distributor because it is an SVA, not an SVDA. SVA = single vacuum advance (it has only a vacuum advance mechanism). SVDA = single vacuum, dual advance (it has both a vacuum advance and a mechanical advance mechanism).

As mentioned, an SVDA is not a match with a 30-2 carb. Those 30-2 carbs only provide around 100 mm HG of ported vacuum. The SVDA canister need 200 mm+ HG of ported vacuum to fully vacuum advance.

The difference between a 205K and 205M is the vacuum canister. The 205K advances 24° and the 205M's canister advances 32°. So the 205k distributor times at 7.5 BTDC and the 205M at TDC or 0°.
I haven't had any issues with good quality points or condensers. If people are running cheap versions, quality issues will arise for sure. Again, some people report years of trouble free issues with points replacement modules.

I do stock the 205M and the other SVA's as well. Sparxwerks.com

Thank you for the info! I didn't know that the 205M was SVA and not SVDA. I honestly didn't know the difference until now.
I really do appreciate all the great info that you guys are giving me, it's definitely much needed. Lol

I think I'm going to try and pick up one of your 205M distributors, it only makes sense to go back with what used to work. I'm glad you told me about the timing, I always timed my 205M at the 0° mark with cylinder 1 at TDC, but I honestly didn't know if that was the correct procedure or not.

I still want to get a pointless unit to try out just to see if it works or not. I'll use the 205M as my main distributor, but try the pointless setup for experimental purposes. I'll keep the bracket on the good 205M after I get it timed so I can swap out with the cheap one.

Will an 009 type distributor work with the 30 Pict 2, or would it be better to just drop a pointless kit into my old 205M? Do they even make a pointless distributor that's SVA and not SVDA?

If you haven't received your order from Tim I would ask him to change to a 34 PICT 3. Then you can pair it with this which is the perfect pairing:

I'm assuming you have the adapter to fit the smaller 30 series carb on the larger dual port manifold? If so, you're good to go with the 30-2 and an SVA. The mechanical advance only Bosch 009 works "ok" with a 30 series carb though some can have a flat spot. I always prefer the vacuum advance distributors over the 009's. With that said, the Bosch 009's are a good distributor for dual carbs that don't provide enough ported vacuum to work an SVDA canister.
Many folks like the points replacement modules but they also either carry a back up distributor with points and condenser or carry a set of points and condensers in their glove box just in case.

If you have a dual port engine in your Beetle is would make sense to set it up to '71 Beetle specs. That would mean a good used or rebuilt SVDA distributor (stock, most aftermarket are suspect when new) and rebuilt 34PICT-3 (not sure about the quality of any aftermarket units).

With a stock single port engine I would recommend setting it up to '67 specs. The very different intake works best with different parts. VW spent a lot of effort getting it right for each type.

Hey @wcfvw69 & EVfun there is not an adapter where my carb bolts on, the 30mm carbs fit right on the flange. Either someone has somehow put a single port top into the boots that are attached to the manifolds, or someone has cut the original 34mm flange off and re-welded the smaller 30mm one in its place. The reason I say it’s been cut and welded is because one of the mechanics that worked on it once said that was what happened. So, I cannot easily slap on a 34mm carb. I’d have to replace the whole manifold. That’s assuming that there is not an adapter that goes from 30mm to 34mm. This is why I am leaning towards sticking with the 30mm setup, it ran great with that setup before, and it will be cheaper to replace those parts.

But, all that being said, I’m not wholly opposed to only going with the 30mm set up. I am open to replacing the intake and upgrade to the 34mm carb and an appropriate distributor if it will result in a better running engine.

The 30mm setup worked great a couple of years when everything was running. Is the difference between the 30mm setup and the 34mm setup a noticeable improvement, or just a slight difference? If it would only be a slight difference, I’ll go the cheaper route, but if the difference will be be a noticeable improvement in power and reliability then I’ll spend the money to upgrade everything.

Find yourself a used dual port manifold and clean it up. Then you can use the 34 PICT 3 carburetor.

I don't think most folks would notice that much difference if you 30 series carb is jetted and adjusted correctly.

I run my original rebuilt 30-1 carb and restored SVA in my bone stock 67' bug. It moves along very nicely. Wink

Yeah, that’s kind of what I was thinking. It ran great with the 30-2 setup before. I just want to get it back to where it was. I still have the old 30-2 carb, so if the jets are different I can swap them out. I’m not sure if they are or not. Plus it’s way cheaper to stick with the 30-2 setup. lol

When I built my 1835 I ran the electronic ignition in place of the points. One day, my car wouldn't start. No spark. Put in a set of points (that I had as a spare in the tool box, like you mentioned), gapped them, and my car immediately ran better than it ever had with the Pertronix. After that, I've sworn off the Pertronix completely.

Hey Mitey62, I’m definitely going to go with a good rebuilt German distributor for sure. I will buy a drop in points kit for one of my old distributors just to see how it goes strictly for craps and giggles. I think I’m going to go with an Empi kit instead of the Pertronix, just based on what everyone has been saying. I’m going to only try the pointless kit after I get the bug running with the good stuff first. I’ll keep the good distributor in the car with the bracket locked in place at all times when running the pointless kit to be safe. It’s just a shame that everything made nowadays is such junk! It’s almost like they don’t want us to keep driving these old cars.

I don't and won't install any points replacement module in my restored distributors. I just know too many people who've been left on the side of the road when the modules crapped out w/out warning. Some people have luck with them but in 35 years, I've never been broken down due to quality points and condensers.
