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.

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.

what's the VW number on those carbs you have? I'd match first the jetting to what they came with originally |

This is great info - so the main jets are different sizes?
I needed to rejet for my new motor and couldn't with the Alt helpers - you just can't find them in different sizes. Ended up get a beautiful pair of 1970 carbs and re-jetting those. _________________ Tom Reay

You can just take out the big lump and put in a standard jet and plug _________________ http://www.thesamba.com/vw/archives/manuals/jim_martin_engine_build.php

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. _________________ Tom Reay

What if you go to bigger displacement -- 1641, 1679, 1776, and so on -- do you use bigger jets? I read a HotVWs article back in the '70s about changing jet sizes. |

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 |

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.

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.. |

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? |
