Adrian Saunders Posted June 14, 2019 Report Share Posted June 14, 2019 My 72 GT6 has cold start enrichment on the front carb only. There is a link tube between the carb’s, but the port isn’t drilled-thru on the rear carb so it doesn’t do anything. Anyone else got this setup?

NonMember Posted June 14, 2019 Report Share Posted June 14, 2019 It's a while since I rebuilt the carbs on mine and I don't recall how closely I looked at the choke port on the rear. It's not a big hole and may not be obvious. I'd be slightly surprised if they bothered to fit the little brass tube insert on carbs where the hole wasn't drilled.

Colin Lindsay Posted June 14, 2019 Report Share Posted June 14, 2019 Isn't that intentional - there's only a choke on one carb? Link to comment Share on other sites More sharing options...
dave.vitesse Posted June 14, 2019 Report Share Posted June 14, 2019 Yes the back/rear carb should have the port drilled through. Dave 1 Link to comment Share on other sites More sharing options...
Badwolf Posted June 14, 2019 Report Share Posted June 14, 2019 I only had choke on one carb (su hs2) for years. Link to comment Share on other sites More sharing options...
Pete Lewis Posted June 14, 2019 Report Share Posted June 14, 2019 If its made correctly with drilled ports you do only have one starting valve but it feeds both carbs with excess fuel used by a number of manufactures Well carbs with holes Doesnt apply to Base CD only CDS > Link to comment Share on other sites More sharing options...

The link is pointless, there is no hole into the rear carb. It does start when cold, but of a pig for a few seconds but then seems fine. Link to comment Share on other sites More sharing options...
Pete Lewis Posted June 15, 2019 Report Share Posted June 15, 2019 Isnt the choke feed tube on a screw held adaptor , take it off there can be a grooved route inside not a direct hole Then I might be dreaming Pete Link to comment Share on other sites More sharing options...

dave.vitesse Posted June 15, 2019 Report Share Posted June 15, 2019 Adrian, If you attach a pipe to the port on the carb and blow into it whilst listening at the air input of the carb, if there is a way through you should hear it. However, if there isn't then there will be resistance to your blowing air in. Don't suck! Dave Link to comment Share on other sites More sharing options...

Paul H Posted June 16, 2019 Report Share Posted June 16, 2019 Not sure if I’m up to speed on this but have you removed and checked the choke assembly . From memory it’s held on by 2 screws just re read the post and understand the issue is with the front carb Paul Link to comment Share on other sites More sharing options...

The car works as is, just quite rough on cold start. Maybe the tube is just to prevent an air leak into the front carb. Link to comment Share on other sites More sharing options...
Pete Lewis Posted June 16, 2019 Report Share Posted June 16, 2019 Well theres something amiss with your rear carb , they wouldnt fit the tube with no hole , as thats just a cost waste Youre hole's has done a runner, and if they wanted to block off the feed they would remove the rear feed adaptor from the starting valve on the front carb ,,, more money saved Anyone with a spare hole post it to Adrian he's lost his Pete Link to comment Share on other sites More sharing options...

It looks original, but no longer functions? Link to comment Share on other sites More sharing options...

Colin Lindsay Posted June 16, 2019 Report Share Posted June 16, 2019 I've got a hole in the toe of my sock which is not meant to be there, so I can post it over, however it may require an adaptor which I'm pretty sure is unobtainable these days.
