Baby Dell's? They came with 26mm venturies, right? Per the carbueretor selection and jetting tech articles in aircooled.net, the venturi should be 3-5mm smaller than your intake valve diameter. 40hp intake valve is 32mm, right? So the carbs could match quite well. I don't think baby Dell's ever had STEEL intake manifolds, and the carb flange bolt pattern is different than for Solex PDSIT, Solex PIC, Kadron and Weber ICT AFAIK. You might be able to make your own flange out of steel, and weld it onto a suitable steel manifold for your 40hp "level" intake manifold flange.
Berg's carb linkage is great since it allows easy adaptation for such a custom design and kind of looks "old" especially if you paint the linkage angle-iron in black. |

So there is nobody in the continental USA who can provide this type of a set up like the above set up from Germany? That is really hard to imagine. Jim |

Rome, thanks for doing the research on the dellortos... I didn't know about that linkage...This might become a winter project (great another one!)... Now I need to get my hands on some 40hp intakes...and start choppin' and weldin'!! |

Sure. Another final detail you might consider is the "stability" of a tall manifold/carb/air cleaner assembly on the small attachment area of the head. You have a potentially large leverage effect with all that weight acting upon the small M6 studs of the 40hp head. If you ever get your custom carb setup done (we wish you encouragement, and pls post photos of it!), consider making a simple brace from the top of the carb body to the fan shroud. I did that for a set of SP Kadrons, using a 2" or 3" piece of "right angle" flat metal reinforcement bracket (L-bracket) from a hardware store. I found 2 carb top body attachment bolts closest to the fan shroud, then only needed to drill 1 additional hole in the bracket so that it fastened to the carb with those 2 bolts, then reached over to the shroud. Use a sturdy sheetmetal bolt in the fan shroud. Also make sure to use a large thick flat washer at the manifold where it fastens to the head so that the attachment nut's force is spread over the largest possible surface area, but don't overtighten the bolts- I'd suggest using the same torque as per the sump plate nuts = 6 lb.ft.
Also, about 13 yrs ago I found a pair of old single-throat downdraft Solex carbs on a Euro-spec Mercedes in a junkyard. They looked "VW-size" so I took them off, then found that the bolt pattern to the manifold was also slightly different than for a VW Solex carb, Kad, etc. I had a local metal fab shop rebush the holes in a set of metal Kad manifolds to match. You could do that also for your combo, that is, to find some cheap steel manifolds and have new holes drilled and bushed. Or, just grind out the existing holes so that you can fit the carbs' studs thru it and use fender washers... Certainly cheaper. |

For that price, I'm not going to try and buy one to see. |

No, not that I know of. As I mentioned before, the only way to get something like that, is to get like Weber 34ICTs for SP and use 1300 heads. |
Do 1300 heads bolt right up? |

Yep, the cylinder opening was still the same size on 1300. It got larger for 1500/1600 series heads. Now, the upper cylinder head studs do need to be longer, the same as needed with the good mid-late 1965 40HP heads. |

I used Vanguards cable linkage set up on my '63 vert. When I was finishing the car I was completely convinced that the cable linkage would be problematic and I would be yanking the engine and replaceing it with a bone stock 40hp. It's about 5 years later and 22k miles and I almost never have to touch them! It took some fiddling around with backing down the accelerator pumps and changing the jetting on the 28 pict1 carbs but this set up has been a dream come true! I'm also running 83mm P/C set with 1.25:1 ratio rockers, reworked repop abarth exhaust, 010 distributor, Judson Magneto (not in older picture), and Knecht aircleaners.

Riechert do a good kit, single port manifolds to fit 40hp, full linkage, and dual carbs. Worked pretty much 'out of the box' - they even jetted them to suit the engine set-up I was having built.

The website (english version) says it's out dated. Can you still order from the website or call? |

I would definitely call, I think he's one of those guys who only checks his email if he's expecting one. Bernd is a genuinely helpful on the phone, his English ain't great - but it's 100 times better than my German
When I was ordering mine, I rang to talk to him generally about what I was looking for, and then he asked me to email detailed engine specs, as he flow-benched the kit to suit before shipping it. _________________ 1385cc 40HP Vintage Speed Build: http://www.thesamba.com/vw/forum/viewtopic.php?t=325587&postdays=0&postorder=asc&start=0

Jim, I started with an early 40 hp case (within a few hundred numbers of being correct for my car) that still was useable and standard. I had a freind cut it for cam bearings. I put it together with a NOS crank, KS main and rod bearings, rebuilt rods, square boss heads, a bus 6volt 200mm flyweel, heavy duty valve springs and solid rocker shafts.
One mistake I made was not bolting the used cam gear to the cam because the gear came loose after about 1000 miles and I had to tear it down.
Something I'm considering locating in the future is a true magneto to isolate the engine ignition from the occasional 6 volt issues.

all I can say is
the stock 28PCI is overjetted for the 1200, otherwise it runs just fine. _________________ '65 Karmann Ghia 'vert

No offense, but that alternator just looks wack with the rest of your set-up. It's like a nice slice of cheesecake with a dead goldfish on top. _________________ Looking for aluminum single port Kadron manifolds. |

shane, good work! The only way you can get those stock 28's to work on a full fan shroud is to mount them waaay up like you did. With such long manifolds, how is throttle response at higher engine speeds?
Mr. Stein, that JC Whitney ad for the carbs would be suitable for a DUAL-PORT engine. I'm not aware of any dual-throat, dual carb kit that would neck down into a single-port's teeny intake manifold ports.
Wishing you careful measuring and success with your manifold fabrication. |

Rome, Thankfully welds can be rewelded! But I am sure there are posters here that can help me. I am starting with single port intakes from a later model and grafting on the port connections from a '65 1200 intake. So except for screwing them up in any assortment of orientations I should be fine. Jim |
