Richard B Posted August 5, 2017 Share Posted August 5, 2017 Does anybody know of a conversion to the bottom bowl of the 175 Stromberg, something that gives a non-leaky blanking plug?(and if not, why not) I've found a Lotus site where an aluminium plug was sealed into the hole. Why couldn't have Zenith brought out a plain bowl without the O Ring and hole for the later emission carbs? Could the hole have a plate TIG'd in?

Richard B Posted August 6, 2017 Author Share Posted August 6, 2017 Brilliant!Do you know are they for a 175, the listing does not say. Quote Link to comment Share on other sites More sharing options...
1968Vitesse25 Posted August 6, 2017 Share Posted August 6, 2017 Haven't seen any. 150's with that type of base. Worth asking the vendor.I suspect they are left overs from converting 175 SEVX carbs (lots of NOS ones about ex US spec TR7) to adjustable jet for older cars.ETA: they seem to have NOS 175'shttp://stores.ebay.ie/N-J-Will.....romberg&_sacat=0 Quote Link to comment Share on other sites More sharing options...
Richard B Posted August 6, 2017 Author Share Posted August 6, 2017 Thanks for the info. I've bought them. Just had a reply from the vendor Quoted Text they fit 150cd and 175cd carbs both are the same these came off 175cdl Quote Link to comment Share on other sites More sharing options...
mikeyb Posted August 6, 2017 Share Posted August 6, 2017 Hi Richard - if the fit Stag, happy to do a deal with you for a couple. Fed up with the whiff of petrol after a good thrashing! Quote Link to comment Share on other sites More sharing options...

1968Vitesse25 Posted August 6, 2017 Share Posted August 6, 2017 4 sold? I've half a mind to ask the vendor for commission! Quote Link to comment Share on other sites More sharing options...
Graham1 Posted August 7, 2017 Share Posted August 7, 2017 1968Vitesse25, You should.Had the GT6 booked in for an MOT on Saturday, took it out of the garage on Friday night for a final check. Petrol poured out of the front carb. Stripped the carb down to check the needle valve, still no joy. So cancelled MOT. Saw this thread on Saturday night and brought two on Sunday after it was confirmed that they would fit CD150s.So to all thank you for the lead.Hopefully MOT next Saturday.Graham Quote Link to comment Share on other sites More sharing options...
Pete Lewis Posted August 7, 2017 Share Posted August 7, 2017 Bear in mind they wont fit a cd or cds carb with adjustable jet only those later ones cdse > with top needle adjusters Quote Link to comment Share on other sites More sharing options...
Richard B Posted August 8, 2017 Author Share Posted August 8, 2017 Correct, but all Stags have the CDSE with the top adjustment. As there is little space underneath anyway. As well as the emission requirements.You should see the contortions required to get your hand underneath each carb to check for a leak! 😎 Quote Link to comment Share on other sites More sharing options...
Graham1 Posted August 8, 2017 Share Posted August 8, 2017 Fortunately or not my GT6 has top adjusters as well, hence the leak.Just ordered some new gaskets so hopefully get them fitted later this week when delivered.Graham Quote Link to comment Share on other sites More sharing options...
Pete Lewis Posted August 10, 2017 Share Posted August 10, 2017 always check the gasket follows the base contours many kits have a full set of evolved gaskets its easy to fit one and find theres a corner not sealed as the gasket shapes have small changes over the evolved years just a thought Pete Quote Link to comment Share on other sites More sharing options...
Graham1 Posted August 11, 2017 Share Posted August 11, 2017 Last night went to fit bases TO 150CD however was not able due to the screw that are required, the current screws are either too long or the short one just grip the threads. I felt this was not quite right. Today went to engineering suppliers and got the following 8-32x11/4 UNC cap heads to do the job. All the screws required on these bases are the same length. I hope this helps anyone else considering this job.Graham Quote Link to comment Share on other sites More sharing options...
Richard B Posted September 24, 2017 Author Share Posted September 24, 2017 I found for the Stag that I needed even shorter cap-Head bolts 7/8" as two per carb were bottoming out. Hopefully this leak will now be resolved. 🙂 Quote Link to comment Share on other sites More sharing options...
Graham1 Posted September 25, 2017 Share Posted September 25, 2017 Update, I did have to remove a couple of mm from each screw however all fitted and no leaks. Bad news this has now lead to new jets and needle to get the carbs tuned correctly.I have access to a good mobile tuner in the Nottingham area (been using him for a number of years now), possible last of the few as people now plug computers into cars.Any interest in having your car tuned at home PM me.Graham Quote Link to comment Share on other sites More sharing options...
Don Cook Posted October 12, 2017 Share Posted October 12, 2017 Did you stop the leak? Float height needs to be set properly i.e. float under its own weight (carbs off and placed upside-down), then measurement set, not still fitted to the car and float propped up with a finger.

Richard B Posted October 13, 2017 Author Share Posted October 13, 2017 Quoted from Don Cook Did you stop the leak? Float height needs to be set properly i.e. float under its own weight (carbs off and placed upside-down), then measurement set, not still fitted to the car and float propped up with a finger. Yes finally. I had some distortion in the base of the carb bodies. A friend recommended "Blue Hylomar" as it is fuel resistant. A thin smear along both sides of the bowl gaskets has stopped it.Its a problem in the Stag as the carbs are installed at an angle on the pedestal (about 30 degrees) so the gasket is always under petrol on one side.I did check the float heights but the were spot on.A fuel injection conversion is becoming attractive...

Graham1 Posted October 13, 2017 Share Posted October 13, 2017 Yes it stop the leak and yes did check the float height, also replace needle and jets. Finally tuned and running fine. I do have surplus bowels if you need any.Graham Quote Link to comment Share on other sites More sharing options...
Don Cook Posted October 13, 2017 Share Posted October 13, 2017 Well Graham, I'm 66 so I'll have one of your spare bowels as it might come in handy. Quote Link to comment Share on other sites More sharing options...
