Thread: Our Jensen Healey restore project, many questions.

    Re: Our Jensen Healey restore project, many questions.

    Most likely the stromberg has a bad diaphraghm or the pring inside has been messed with. Propbably the former item. You can, if you're clean about it, replace that bit with the carb on the engine. If you want to pullthe carbs, they aren't hard to rebuild, but there's a bit of a trick getting them synchronized correctly.

    Re: Our Jensen Healey restore project, many questions.

    We will look into rebuilding them, Unfortunately I have to leave this to my dad for the time being, as I will be leaving for Oregon and Washington on Friday. On a side note, It sure would be nice if the engineers had made the hood to rise higher. It takes a toll on your lower back to work on this car, I have been doing most of the work on my knees.

    This site is awesome http://www.carbkitsource.com/carbs/t...g/2barrel.html but we are not sure which model Strombergs we have. How can I tell? Those exploded views and descriptions are pretty sweet. I need like, "Stromberg 101" my Edelbrock came with a DVD that made tuning and adjusting dummy proof, I have a feeling it's just as easy with these, once you have the knowledge under your belt. If someone can point me in the direction of a manual, preferably a pdf, or How To on the rebuild, I am sure myself or my dad can rebuild these. I see that Summit has rebuild kits, but I need to know my model number first. We are not with the car, but I can make a trip to it to read nay numbers stamped on it, unless someone can say which models we have based on my photos. Hmm??

    Most of the Stromberg info I see on that site is for earlier carbs. I didn't see the 165s that are used on the Jensen Healey. Order the rebuild kits from Delta and then go on YouTube and search for "university motors stromberg" there's a three part series where they rebuild a Stromberg as put on an MG. Very similar to the JH excepting for the linkages.

    I had a step by step photo catalog of rebuilding JH Strombergs, but I can't figure out what I've done with the photos.

    US spec JH's have Stromberg type 175CD carbs.

    For me, the height of the bonnet has been less of an issue than the latch. If I don't remind myself to wrap a shop towel around it I'll end up with a divot in my head.

    Re: Our Jensen Healey restore project, many questions.

    Thank you very much for the info, I will have to get the rebuild kit. The hood latch left a nasty bump on my cousins head, and I just know I will do it someday soon. Those Youtube videos are a good find. I am going to watch them right now, if I can, I will get my dad to take photos. How To's are priceless sometimes.

    EDIT: Jody said Stromberg <span style="font-weight: bold">165</span>, and PC said <span style="font-weight: bold">175</span>. I just want to clarify here, I am not used to these carbs.

    Well, mine say 175 on top.

    And my old copy of the Haynes Zenith Stromberg CD Carburetor Workshop Manual only references types 125, 150 and 175.

    I was incorrect in my post. I believe I either fat fingered it or hadn't had enough coffee yet. 175 is correct.

    Oh, and stupid trick for the hood latch. Get some hot water pipe insulation. The round foam stuff with a slit in it for fitting over pipes. Slip a length of that over the latch and put a little tape on it to hold it in place. It's a noggin saver.

    Re: Our Jensen Healey restore project, many questions.

    Does anyone have any advice for getting the bottom bolts off the carbs? The front one seems impossible to access. I heated and bent a wrench in effort to get it, but still have no room to rotate. (It was a crappy wrench, not my Craftsman)I am fearing I might have to take the IM off.

    A stubby or cut down open end wrenchand a lot of patience. It's only slightly less annoying with the manifold removed.
