Colin, thanks again for publishing this excellent guide. A couple of notes:
Some of the diagrams have vaporized; I managed to get by without them but reposting them would be beneficial, especially for those not yet familiar with the nomenclature.
It might also be useful for the guide to specify that the procedure applies to Buses with an OEM (DVDA) distributor. If your Bus is cursed with a 009, you're kinda on your own.
The intake hose mentioned in Colin's spiel on emissions controls is missing from every '72-'74 Bus I"ve seen. I don't know how critical it really is for the engine, but I've replaced mine. It is a 63mm (2.5 inch ID) hose about 80-90cm long and is secured with a hose clamp at the airbox inlet and two lugs on the engine compartment wall near the right elephant-ear.
A good-quality, two-layer neoprene replacement is available from Pegasus Racing (part # 3630-2.50-3FOOT) for about $20. I haven't been able to find the OEM paper hoses anywhere; they are a different size than the common heater hoses. _________________ 1989 Westy

A) 009 can work, but I am not going to provide the work around solutions for an 009, it would make mincemeat of the already hard-to-discern logic behind these carburetors.
SVDA can work, too. Like the 009, without a retard at idle, you have to choke off the central idling circuit to get a decent idle. Then you have a poor transition to the main carbs off idle, etc.
B) That hose is the cool air supply. It is not emissions related. I do recommend that we pony up for a hose that can reach the right side scoop area.
As parts dry up, we will need to exercise ever-greater creativity to achieve anything like the driveability of the original engineering. It can be done.

Colin, would you recommend that I replace the weber's that I have back to the originals?
I have a 72 Westy 1.7 with weber ict and can not get them to co-operate with each other.. _________________ 72 westy 1.7 dual carbs |

Any chance you could repost those missing images from your first post?
Great info, thanks |

Perhaps a mod or Colin will edit the first post accordingly, since the picture links seem to be broken. _________________ Learn how your vintage VW works. And why it doesn't!
