These are the holes for the progression cirquit, right? If so, should it
not read "below the throttle plate"? Or is my memory incorrect? Anyways,
it was not to be picky, just hard to spot for a novice if he/she was to
look in the wrong place..

Yes, progression circuit. The ports are above the plate.
Throttle closed, there is no flow from the ports.
As the throttle begins to open, first one (very small) port
is now "below" the plate and so has vacuum pulling fuel
from the pilot jet.

As throttle plate opens (moves "up"), more ports are
exposed.

Yes, exactly. When you said above I thought as in roof, whilst they are
on the floor(If the carb was horizontal.. Which of cause it is not.. My
bad, thinking of horizontal here, as in all the carbs I deal with at work...

Thanks for all the response guy's.
That evening I went to the shop to buy me some jets...
Unfortunately he didn't have had any but i went up reading a book about the
carbies.
I have a 31PICT-4 which is, to what I read, pretty unusual.
The difference (there might be a lot more) is the acc pump ánd on a 31PICT-4
there is
suposed to be some kind of thermo device mounted with a bracked on top of
the carb
pusshing the trottle lever open (like the shoke does) without actually
moving the shoke.
This device is non electrical and is suposed to work on temps below 15 C.
I hope I do make some sense..

Since I'm not able to trace the device down, I've got myself a 31PICT-3.
Smaller pump and without a big brass bold into the reservoir. Is this the
only difference?
Before I change it, I still do want to clean the original up, having had
advice here on how to do it.
And where to look!
Thanks all for your input, it is VERY helpfull

Roger
