May 29, 201016 yr comment_440870 Given the inherent ploblem with the stock Aisan carby's running rich due to the floats, I have decided to go down draft Weber. The question is, which Weber (and jetting) best suits a stock 1.8 3Tc engine. Be mindfull, the aim is maintain factory econmy or better. Sadly performance takes second place... at the moment. :blinks: Report
May 29, 201016 yr comment_440901 32/36 weber from a Ford Cortina or Escort. Jetted for 2.0L so close to the 1.8L of the 3TC Report
May 29, 201016 yr Author comment_440922 Good old 32/36. Economical primary, guttsy secondary. The Cortina/Escorts ones seems to be a bit more abundant too. I was hoping someone would say twin 32 or twin 34 as I already have a 32 DAGV (already on a 3Tc manifold but i'm guessing too small) and a 34 ADFA (off a Fiat spider) Report
May 29, 201016 yr comment_440926 My 4AC runs a 32/36 DGAV with 130primary 125 secondary jets and is sweet! Runs down stock BA Fal-con's in the first 3 gears! Report
June 1, 201016 yr Author comment_441702 Cheers for the advise. it appears that a 32/36 is going to be the way to go. :D Report

Been looking for baseline jetting sizes for a stock 3TC, but bit of a mix: http://www.3tcgarage.com/viewtopic.php?f=1...baseline#p39639 For the 32/36 DGAV with the water choke, the baseline settings for a 2.0L ford are: http://www.racetep.com/webercarbjet.html primary/secondary: main: 140/140 air: 170/160 idle: 60/50 em tube: F50/F50 Looking at other 1800cc OHV engines from golf, subaru and fiat as a guide: http://www.ausubaru.com/wiki/index.php?title=ENGINE:WEBER http://www.1800vw.bizhosting.com/progcarbtune.htm http://www.mirafiori.com/archive/Gener/94567.html Bit of a mix, shouldn't be to far off the 2.0L Ford jetting. Just have to experiment. Report
