Kits and how to for dual Carbs to the 40Hp

[Rome]

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.

Is anyone familiar with this kit that says it is "bolt on" for the 40hp engine?

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

[james m. stein]

That is exactly why I am asking the forum.

[henry roberts]

wouldn't that just be the empi 40 HPMX kit labeled incorrectly.

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.

[james m. stein]

Shane6: did you put in a new bottom end with the bigger P&C's? Jim

all I can say is

the stock 28PCI is overjetted for the 1200, otherwise it runs just fine.

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.

The kit I posted:
http://www.jcwhitney.com/autoparts/ItemBrowse/c-10...8510689731
is in fact not correct for the 1200 40 HP and is for the 1500/1600. I will make my own manifolds and set up as others have done for my engine.

[Rome]

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.

[james m. stein]

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
