First, I want to say that I think it’s amazing that this is even possible. You see, I’ve never even met Bruce Lancaster; don’t know what he looks like, never spoke with him on the phone and he’s quite a distance away. This is all possible because of Ryan- and the other editors- and technology. Thanks! Well, Bruce and I have wanted to do a thorough and lengthy Stromberg 97 tech but we’ve been trying to work out the logistics; how to post large scanned files, where to put them so we can update them, making it possible for you to add your two cents etc. This will take us quite some time, as we are going to do a thread on each of the following sections. As a matter of fact, it make take us years. I have a LOT of scanning to do, thanks to Bruce. I may add or combine some of the sections later….

Well, get to postin' cause I got three 97's to rebuild this weekend and I need to know how to get the emulsion tubes out. They are for the Ramrods Hambster(sorry..HA/GR), and it has to be ready for next Saturday's Mo-Kan gig! HURRY!!
I didn't see a title on power valves. In my opinion this is the real secret to tuning multiple Strombergs, much more important than main jet selection. Changed my power valves and dropped 5 whole seconds in the 1/4 mile.... I'll be looking forward to these articles.
we won't be that far for a while but here's a quickie...... you only need to tap 3-4 threads, that's plenty and just as an extra safety precaution, I kept shooting mine with PB Blaster for a coupld of days......everything came apart easily... http://groups.msn.com/FordFlathead1...essage=40106&LastModified=4675519650699616495 http://groups.msn.com/FordFlathead1...essage=39651&LastModified=4675519751646841648 http://www.tr6world.com/stromberg_carbs.htm
Heres some advice.....DON'T DO IT. Unless you can actually see they are damaged there is no need to replace the emulsion tubes. You will do more harm replacing them. If it ain't broke don't fix it...
You can't see if the little holes are collapsed or not, unless you pull them......however, I agree, that some things are better left alone....
I agree that you can't see if the holes are collapsed, but how many have collapsed? Very few I bet. You'd have to have the best jet wrench in the world and arms like King Kong to collapse an emulsion tube
BTTT for more stuff coming. Next. we're going to post tools--tools you need, tools you want, tools you make. We will show original '30's stuff, hotrod stuff, and how to make emulsion tube puller, power valve setter stuff, fuel level gauge, and later a top straightener. By the way, do take out the tubes. Tools needed are simple and cheap, and those little holes do get dirt in them. If holes are plugged, fuel mixture curve will be deeply wierd, and you'll be fruitlessly chasing your tail with jet swaps forever. There will be more parts ID information, and more on techniques of fixing. And mebbe some theory to quarrel over, too...
OOPS, my mistake, I was thinking of the the vacuum operated ones in the 94s that some folks have so much trouble with in multi carb setups. I've never heard of that problem with the 97s and was always told it was because of the vacuum power valves. Maybe it's because a backfire through the carb won't trash the ones in a 97. Sorry
Stromberg power valves are mechanical, opening when the accel pump reaches a certain point in its stroke. This means that first, they open at the same point in throttle opening no matter what, whereas vac changes caused by multiple carbs make the valves open early on 94's, and second, they are immune to backfire damage, though I must say I've never experienced this in a zillion miles with 94's. The first point makes the old primitive Stromberg easier to set up for multiple use, especially in the good old days when there was little choice of vac settings on power valves. Preview: I have found material on setting Stromberg power valve tip-in point, and we will be making a tool for the job! Get out you crayons and hammers!
Can we do fuel level tool tech first?? Do you have a throttle body that is loose for a bushing rebuild tech?
fuel level tech is first......i found an old oil level at one of the swap meets that looks JUST like the original tool (brass encloser, glass tube inside, threads on the bottom.....i didn't buy it because it was too large, over-all and it was $$$......however, i wonder if i could find one at mcs or mcmastercarr......the pc of hose would be cheaper and easily accessible by all, though..... uh, i'm sure i have a loose stromberg....just HOW loose should it be? edit: that could have been a water level sight glass for like an old steam engine or something....i'm looking for a pic
Do it with the hose, convert to sight glass when opportunity arises! Drill out fitting to max, use biggest tubing you can adapt...simple bracket/wire twist to keep it vertical... Any loose is too loose! Let's rebuild one of those suckers! "Speak softly and carry a tight Stromberg", or something like that...
Flathead Youngin and Bruce, I don't know if this serves a purpose here or not but.... I took your complete hamb article on "Tech Stromberg Emulsion Tube Removal " and converted it to a self contained PDF file. PDF stands for Portable Document File and that's just what it is, Take it anywhere, transfer the file thru emails or file with all stromberg articles on your harddrive or cdr. The Complete Emulsion tube Thread with all persons involved is intact with all the attached pics (including enlarged pics) so that people can easily store it on there hard drive and use it anytime, anywhere without haveing to be connected to the net while viewing the tech article. In essence, I could easily convert all the Stomberg tech articles as you complete each one... I could compile them into seperate PDFs. Then all the related articles could be easily kept in one area on the hard drive or easily burnt onto a cdr as a 'tech book' of sorts... sound interesting or useful? Like I said, Maybe this is not what you fellas are looking for but if the idea of easily transfering the complete collection of all 97 articles on one compact disc appeals.... I could email the article to you if you are interested in seeing how well these threads/articles convert to pdf form Tech _ Stromberg Emulsion Tube Removal - THE H.A.M.B..pdf 3,120Kb
There are bits of this startup all over...I think there's one on carb and parts ID. We started and crashed...and all is kinda hard to coordinate, since I can't post pics.
that would be good to have and keep......nice for emailing people quickly.... jeffholmes at adelphia.net
Speaking of throttleshaft bushings; A little thingy I'm doing lately on all of the 117 carbs I sent out last year, (yes, I count) is to tap the very outside end of the of the bushing 5/16-24, only two turns, then ream to .278 (.001 tighter than spec). Standard throttleshafts being .275, this leaves one and a half thousandths all the way around. Finally, use a dab of high-temp wheel bearing grease inside the bushing. The new threads capture the grease and keep it there for avery long time. This little extra step makes for almost an air-tight alibi. Another 2 cents from yer uncle.
Jeff, Let me make sure that I can do this Again, I had my computer take an early retirement and I lost 7 years worth of data/pic/files/programs. Not to worry, I was able to extract all of the 120GB hard drives contents and I'm working on reinstalling Adobe Pro and getting everything set up again. (The old drive was/is fine, The computers bios or maybe the backup battery caused the problem) I Will keep you posted and email the ppdf to you once I get the new computer up to speed
hey, don't get yourself in a hurry, poor ole' bruce has had his foot up my butt for quite a while now..... with work, kids and trying to build a hot rod.....i've pretty much just jotted it all down as i get a chance to do it.....rather than just setting aside the time and making an independent project out of this.... we'll get her though!
