Northernstar002 Posted March 25, 2015 Share Posted March 25, 2015 Afternoon, Just bought a twin carb refurb kit from Holden.co.uk. very cheap at £34 for both carbs.I had a problem with my old jets in that they were stuck fast in place and the choke cable couldnt budge them. The new ones seem to fit well but they are not returning fully by themselves. With a little push upwards by the finger they return but I cant be doing that on every cold morning. Do I need to re-centre the needle? Do I need new return springs?Thanks for any comments, Quote Link to comment Share on other sites More sharing options...
piman Posted March 25, 2015 Share Posted March 25, 2015 Hello Northernstar, you need to ensure the jet is centred whatever else. If they are then new springs are you next option, they should move up with a positive action.Alec Quote Link to comment Share on other sites More sharing options...
Northernstar002 Posted March 25, 2015 Author Share Posted March 25, 2015 Hi Alec,Thanks for that. I received steps on how to do this with the kit so I'll get on that tonight and see what I can do.cheers, Quote Link to comment Share on other sites More sharing options...
RobPearce Posted March 25, 2015 Share Posted March 25, 2015 Also make sure there's no grit or muck in there that could be jamming them.That said... My brother had a Mk2 Spit with sticky jets, probably worse than yours. In normal use he hardly noticed, because pulling the choke out worked, then once started the engine vibration was enough to persuade the jets back up when he pushed it in. The only problem was if you got in when it was already hot, pulled the choke out of sheer habit, then realised you shouldn't have. Quote Link to comment Share on other sites More sharing options...
Pete Lewis Posted March 25, 2015 Share Posted March 25, 2015 then when all else fails start bending the crappy rods and levers so there's no binding , and the coil spring returns the jet back to its adjusting nut faceset the fast idle cam to give about 1500 + rpm on full choke remove the inner cable and grease it , then set the choke fully off with knob 3mm out of the dashPete Quote Link to comment Share on other sites More sharing options...
