emulsion tubes are sometimes a little jammed in there, get a needle or something and use friction ot pull it out since you don't have the weber tool. The tubes will be F50, they stay the same for a fair share of cars.

With the mains, is the primary 150 and the secondary 132? that looks too lean on the seconday. My specs on the A14 right now (38\38dges but applicible for capacity):

main jets 145\145(might go 155\155)
185 air corrector jets
size 4 venturis
55 accelerator pump jet
40\40 idle jets (need bigger)
f50/f50 emulsion tubes
