Gspec Posted May 29, 2010 Report Share Posted May 29, 2010 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: Quote Link to comment Share on other sites More sharing options...
bruce Posted May 29, 2010 Report Share Posted May 29, 2010 32/36 weber from a Ford Cortina or Escort. Jetted for 2.0L so close to the 1.8L of the 3TC Quote Link to comment Share on other sites More sharing options...
Gspec Posted May 29, 2010 Author Report Share Posted May 29, 2010 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) Quote Link to comment Share on other sites More sharing options...
Suziefox73 Posted May 29, 2010 Report Share Posted May 29, 2010 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! Quote Link to comment Share on other sites More sharing options...
Gspec Posted June 1, 2010 Author Report Share Posted June 1, 2010 Cheers for the advise. it appears that a 32/36 is going to be the way to go. :D Quote Link to comment Share on other sites More sharing options...

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. Quote Link to comment Share on other sites More sharing options...
