BIG STU Posted August 20, 2017 Share Posted August 20, 2017 Hi everyone. I was wondering if anyone could help me out. I have recently fitted a new webber 32/36 dgv to my 77 coupe. I know that these are a common replacement for the original carb's. But I was wondering if anyone out there could help me out in relation to the mixture screw adjustment . Please can anyone tell me how many turns of the mixture screw it should be in relation to the car running it's best.or at least a good starting point towards it running better. The mixture screw at the moment is screwed out 2 complete turns from the stop position. But it doesn't feel right and seems to be sooting the plugs up quite quickly If anyone could give me any pointers or advice to try and sort my carb out. I would be very grateful. Cheers Stuart.

H-400 Posted August 20, 2017 Share Posted August 20, 2017 Just checked my Haynes manual specialised on Weber carburettors. Your carb is included together with some lookalikes. The chapter "adjustments" and "tuning"is rather heavy, the part tuning refers back to adjustment and so on... I can scan the pages and mail them to you, it is in English so not a problem for you!

plumster Posted August 25, 2017 Share Posted August 25, 2017 I had mine refurbed & then set up at Rally Equipe, Bury, on the rolling road, it had never run as smoothly, well worth the dosh. Just a thought if you are still having problems. Quote Link to comment Share on other sites More sharing options...
BIG STU Posted August 25, 2017 Author Share Posted August 25, 2017 Thanks for letting me know. I really appreciate it. My carb is new. So when I get some dosh I will get it rolling roadedicated. That way it will be spot on. I was just hoping that some one might remember how many turns they turned there mixture screw out to get mine as close to been perfect. I will let you know how I go on. Cheers Stuart. Sorry I forgot to ask how much is a rolling road these days. Quote Link to comment Share on other sites More sharing options...
opel2000 Posted October 8, 2017 Share Posted October 8, 2017 Right then done a few of these in my time and need to see if I can remember. If I remember correct, the mixture screw is turned out until the engine starts to "hunt" or run too rich for a smooth idle. Then the Mixture screw is turned back in until engine note becomes steady. Idle screw is then turned in (after already being backed out) to lean out the idle. Apologies but this is the best I can remember, but it is the leaning out of the carb where you need to progressively turn in the mixture and idle screw, to give you the smoothest running. Dead simple and brilliant Carbs, and if you follow the above steps you should quite easily get there. the thought of mixture screw being out by 2 full turns as a base setting rings a bell. just give it a go you'll get there. I had a 2.0S rolling roaded with one of these carbs as I couldn't get a smooth enough idle, turned out I had increased flow through the engine so much that it was pushing out over 130BHP that they had to put in different idle jets.

Not as clear as the instructions I was supplied with my DGV's but it is all there.... As a thought does anyone know off hand whether these are still available new... As at one time Weber produced a whole conversion kit for the cih and it really was a brilliant kit. Last time I tried to buy one back in 2007 I struggled to even get hold of a DGV Carb, and was told by various suppliers that "Weber had stopped production of the DGV/DGAV" IIRC I sourced one form a US supplier that was intended to be fitted to a Jeep, which was a common conversion in the US Apparently.

BIG STU Posted October 9, 2017 Author Share Posted October 9, 2017 How cool is this . I am so glad I asked the question about these weber carb's. Especially with it bringing people together to help and support each other with there manta passion. Sorry I am just having a nice moment 😢 Thanks everyone you've made my day. Especially after my mum having an operation for cancer last week. Take care and enjoy your car's and life. ☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺ Quote Link to comment Share on other sites More sharing options...
Dimpas Posted October 10, 2017 Share Posted October 10, 2017 I have finished ( almost) the restoration of my mantas Engine 13S. I bought a new Weber carb too ( 32/34 DMTL) and i am waiting for a timing light and for a digital RPM meter. Then i will have the tools to follow the procedure to adjust correct the static advance, the idle and the mixture. Just be sure to have all possible vacum leaks sealed and no air enters after the throtle Quote Link to comment Share on other sites More sharing options...
