What jets should i be running on super with 2 strombergs sea level. i have 42 and 69 in them now. motor is stock with dual point and offy 3 carb with center blocked.
IF the plugs look oil fouled, I don't understand the fuel issue..I would be wondering where the oil is coming from.. Duane.
Stromber 97 I do not want to interfer with this thread but I had a question regarding my jetting I have 0.45 main and 0.65 power valve it runs rich at idle made all of the adjustment I may need to change the jet to a smaller one possibly. I have a dual carb 97 strombergs set up on a V12 Lincoln flat head. Let me know Thanks Frenchy
If you are running two 97's. you have to run one as the primary and the 2nd as the secondary. The base on the secondary has NO mixture screws and runs lean. These bases can be purchased on SpeedwayMotors.com
With the center 97 blocked off you need to run both 97s so you get equal air fuel to the engine.. Duane.
Idle and off-idle circuits are significant well above idle, and main jets cannot influence idle mixture. There is a gap between idle and serious flow from jets that needs to be dealt with! You need to understand what the carbs' several different circuits do and when they are effective before you think about this. Get the easy to find '38-48 Ford bulletins (worth their weight in gold for many things) and read the chapter on how the Strombergs function and the chapter on rebuild before you start changing things that have nothing to do with the problem at hand. On the fouling issue...is the black stuff on carbs fluffy and dry, or is it oily? Worry about air cleaners and test with them off if you are running the little chrome ones. Some of those are marginal, some are utterly inadequate.
"No Strombergs were killed or injured during this post. . . " But notice his highly ethical and sensitive treatment of Strombergs! He has VALUES.
Someone just posted this link: http://norgv8club.org/norg/index.ph...rs-and-tech-tips/category/9-service-bulletins Go to second item on operation, scroll past the Ford carb and study the text and diagrams of how Strombergs function. Learn what the several different circuits do together and seperately before you start deleting random functions or altering the wrong circuit. Or don't.
I know this is an old post, but thanks for the bulletin source. You just helped me understand one of the possibilities for my dual 97 setup bogging at speed. Thanks
Still haven't installed the Edmunds 2X2 on my 47. I now have so much information, and disinformation that I go out and look at the setup, and go back in the house....If you ask five people for opinions, you will get six opinions!
The internet is a HUGE improvement in our information base, as you so rightly note!! Go ask Ford how a Stromberg works, and the old bulletins only give you ONE lousy answer. Ask on the internet how one works, and you can get hundreds of completely different answers almost instantly! Your Horoscope will help you choose the one best for you and your feelings today.
Hi Mike, I kind of know how you feel. I waited 6 months after my rebuild before adding dual strombergs. There are a handful of guys here that you can listen to, who are on the same page.. I'm still working the bugs out but duals really made my 8ba 276 come alive in town. What motor are you running? What carbs have you got? are they matched up? The Pres of Dallas early ford V8 group is running dual 94's on his 35 pickup. That baby goes. My 53 will go pretty good up to 65. PM me. i'm just east of you. There are a few decent mech's around too. Bill
What a load of rubbish. I know this is an old thread but heck where do these ridiculous theory come from??
Well, I've seen that on the interweb, so it must be true. Ford just forgot to include info in the "how it works" bulletin on the benefits of removing the circuits that feed half the engine's operating range...
