Dizzy carb combo on 1500cc type 1 engine

[Rockmud]

I have an engine code of HO, which I found is a 1500cc 53hp gem. It has a H30/31 PICT carb and the dizzy is 111-905-205M. I saw an article that states this particular dizzy is meant to run on a 40 hp motor. My motor is not performing quite right. I wonder if you wise people might be able to suggest a good dizzy carb combo for this engine. I'm new to VW air cooled and have no idea where to start finding this information. Thank you in advance for your input.

I believe the 205-k distributor paired with the solex 30 pict1 carb is what you want. Both are available rebuilt, and to purchase in the classifieds here.

Also, make sure all cooling tins and engine to body seals are in place along with a functioning thermostat.

111-M is OK for such an application if the advance works. It's not stock but it's in the same "family" of distributor types. If it works right that is and set the timing correctly. I'd still prefer a 113-K though.

(Also: with an H30/31PICT, I'd want a 113905205M or 113905205T)

Now, In my opinion, the factory installed 30PICT-1 used on the 1500 engine was the best carb that DVG ever made for VW. (There is a different 30PICT-1 that was used on the 1300 engine, and those should only be used for such in stock form)

The 30PICT-1 was the last carburetor that DVG made for VW that lacked any kind of emissions modifications. Just a simple Solex style carb whose 1500 version has an Enrichment circuit ("Power Fuel System" as VW also called it)

Hey guys thanks so much for the info. I really appreciate it.

I have just acquired a 67 HO code beetle that is missing a distributor, though it seems the original carb is with it. Any reason I could not use my 80's vintage Brazilian 009 on it?

Thanks!

ccowx the 009 will work in your engine. My HO in my 67 is running a 009 but I want the 205K dist. for mine, I think the engine will run cooler and smother.

[ccowx]

Good to know that the 009 will fit. Am I correct in understanding that the 30-1 carb is compatible with the same svda dissys as the early 70's 34-3 dual ports? 113 905 205AJ for example? I may customize the advance curve anyway.

Thanks!

Agreed and understood. I would prefer to have the vacuum advance and all that, so I am pleasantly surprised to know that the HO code engine uses similar dissys to the later DP/34-3. Seems the 34-3 and 30-1 both have similar ported vacuum hookups if I am understanding correctly.

Thanks!

No, the 30PICT-1 carbs that came on 1966-67 era engines doNOT have a ported vacuum fitting. You find that on the "lets throw every thing you can think of at a carb" the bastard-child H30/31PICT that never came stock on any VW.

Ok, back to trying to find some sort of svda type option for this one. I don't want the vac only unity, other than for show, so whatever goes on won't be stock.

I am not convinced that the sva is going to work well with today's gas and I am not sure I know how to tune one. I also do not know of a replacement diaphram for these carbs and they rarely work after 50 years. If I am wrong about the efficiency of this distributor or if anyone has a source of replacement diaghrams, please let me know.

I am familiar with the svda carbs for tuning. However, since the carb has no ported vacuum, that kind of makes it all a moot point. I need to change the carb if I want to use the svda. I do like the idea of using the center section and 34-3, so that is one way I may do this.

My other option is to use the 009. Not ideal for highway use but it will work. I recall the max advance is 32-35 for the sva and it is not far off the max for the 009. There may not be that much functional difference. It does not appear that there was much extra advance built into these sva distributors for steady cruising.

Thanks!

I hardly drive my Bugs any more, but back before I stopped driving my Baja, I had for many years been using a 30PICT-1 and matching vacuum-only 113905205K distributor... and this is on a 1600 dual port so I have to use a base adapter for the carburetor. This works, and it works well. Some people say I'm killing top end performance but I never noticed it. (I've alternated this with a matched VW_410/34PICT-3 carb and 043905205 distributor.)

I just like the simplicity of the 30PICT-1. It was, after all, the final carb made by the German Carburetor Company (DVG) for VW, prior to them reworking the carb design to make it more emissions friendly (and consumer unfriendly)

Oh, and this is with E10 fuel and at 4800 foot elevation. Ethanol laced fuel has a little bit less overall power density, but other than lower fuel economy, it runs fine.

So after reading and following this thread I am morae confused than ever. I have an HO engine that is OG to my 67 bug, When I bought this car it came with a 009 dist. and ran well but the carb. leaked like a sieve, I bought a new carb. and the one the local Aircooled shop gave me is a Brosol/Solex carb. The box it came in states its a P/34PICT but also says 31 PICT on the tag. the carb. itself says H 30/31 PICT, the car runs well but I want to go back to the OG 205K dist. that came stock on these engines. would the 205K dist. work with this carb. and be a good match to this carb. Thanks for any info on this.

[ashman40]

[Big Bill]

Thanks ashman40 for the info. Mine does have the D port and also the port just below the carb. flange. I read glutamotos write up on his tests but will have to re-read it a few times so the info will sink in. I wonder what that port below the flange was used for? Thanks again.

[ccowx]

We keep coming back to the SVA dissys. As I said, in my world they seem to be a non-starter for the simple reason that they are both unavailable and also not very tuneable. This was why they were all replaced at John Muir's urging in the early 70's. Am I correct in this viewpoint or is there a source of diaphrams etc that I am not aware of?

Thanks!
