ok, thanks. i was thinking about all the exhortations to 'use the search' so often aimed at people asking questions. turns out there's a bunch of hidden info on the site that would never turn up just using the indexed material.
what does samba dog say? |

so how does the archive work? if i go the index page there is no link called 'manuals' yet that's what's in the url. if i shorten the url to just 'manuals' there's a whole page of info which isn't in the index.. |

Yes, sometimes even a change in exhaust on a stock motor can warrant a jet change. You can change the venturies for bus ones (26mm) as well for better flow.
I played around with mine on the 1600cc a bit before I bought the 36 dells for the 1904cc. This was about as good as it got when I was playing with it with the 26mm vents.

the differently sized main jets (and air correctors) are due to the air cleaner design, if you use the later cleaner you can jet them symetrically
I thought altitude correction main jets could actually be adjusted, but I would definetely not trust a 40 year old diaphragm  |

It seems like you could, but you can't.
No threads where the jet goes into the venturi - that's what the o-ring does, and the fuel bowl and even the float are a different configuration.

You can just take out the big lump and put in a standard jet and plug

This is such a nightmare. lol
Anyone have all the paperwork in english?
It seems like a vital resource not to.
I need to know what jets i should have in 1967 32 pdsit's on an all stock 1600 with a header and single QP. Also has a pertronix vac distributor.
Plan is to put a wideband on it and jet from there. But until that comes in id love to have some input on what people have found works best.
We do have the air filter that requires the staggered jet setup.
Thanks in advance. Any info is appreciated. 
Dave

Ok, the PDSIT 3. The actual measurements of tube heights are;
Acc. tube 12mm
power tube 15.29mm
PDSIT - 2
ACC tube 14.5mm
power tube 11.5 mm
I will correct the heights to match the -3.
jetting will be as follows:
PDSIT-2
24mm venturies
Main 132.5
Air correction 150
55 elect idle
PDSIT - 3
24 mm venturies
Main 130
air correction 120
55 elect idle
Per the chart, I should not have the power jet at all. I will leave them for now rather than remove and plug or just plug.

| according to the table, on a 66 the acc pump tube is 12mm away from the gasket plane, the power jet is 15mm away, and you should be using a 1,5mm thick washer under the needle and seat, I would only use that washer if the carbs turn out to be 66s |

Ok, both carbs have 3 tubes. I'm not sure which is the power jet tube. The vertical tube is the same length. The other two tubes, over the venturies are slightly longer. one is about .030" longer and the other is about .070" longer.
Which is the power jet tube?

| what are the engraved VW numbers on the carb bodies? |
There are no engraved numbers on the carbs. The number consist of stamped, raised (cast) or aluminum tag. These are not the original carbs. But were NOS three years ago.
Complete info as they are set up now, using the orignal oil bath air cleaner
32 PSIT-3
B 6 116 (stamped)
VW 41-2 (stamped)
Aluminum tag 311 129 026B
23mm venturies
main jet 130
air correction jet 240
idle jet with electric 55
This appears to be a 65-66 based carb.
32 PDSIT -2
5040364 (stamped)
VW 129 025 AX
Aluminum tag 311 129 025AX
23mm venturies
main jet 135
air correction jet 180
idle jet with electric 55
It appears that this is 64 based carb,? I need to convert them to the 66, 1600 version.
I think I am on the right track, I just want to make sure.
I have a stock single port 1600 converted to 12v, counter weighted crank, everything pretty much stock.
