I found my sander. Not much use. The flanges were so concave I had to use a file. I only took two pictures of the flanges because I'm not really satisfied with the way they look.

With that done, I put on the first coat of paint. One run, See if you can find it.

Added six pictures to Webphotos to show the progress. http://good-times.webshots.com/album/564126102jBBKyv

Next steps are to put on the finish coat, file the mating surfaces and polish the bore.

Starkweatherr and all,
I would like to get this thread back on track a bit. I depend and look for all of your Stovebolt experiences. I have stayed away from a vendor due to the "bad press" I read here, I have gone to good vendors based on the "good press", I have gone to bad and good vendors despite what was said regardless of what was said about them. This is working for me so far. I take what I read, make a decision based on the facts at hand and go with it. No regrets if I do all I can do based on all of the information I have at hand.
All I ask is a heads up on both good and bad stovbolt experiences. A nice tight explaination of the good and or bad. We can follow up if asked for further info add as requested.
Along these lines I agree with Czechman - settle it first, and then post the brief. The system works, it is working well here, and I am glad to know there are folks out there with a customer satisfaction belief as mine.
This being said: I would like to throw out a major concern with Vintage Speed and will post seperatly, and accordingly. I will refrain on details right now pending outcome and it is not my post, but a you can see from a prior post, it is not heading in the cutomers favor at this point. I will post it independantly and at final outcome. I hope we keep control on this and do not get to a point of our threads being edited and deleted out.
Thanks for the ear,
Cavebull

I rejected the Langdon's setup because, even though it was praised by many here, I thought it looked ugly. Kind of like a Frankenstein conversion. I didn't like the look of the adaptors. I thought the carbs looked all wrong for the year and engine. I hated the air cleaners. That doesn't mean Langdon's isn't for you. It just wasn't for me.

So, I run two Model B's with no chokes at all. The only problem I have is low gas mileage because, well, I can't seem to keep my foot out of it. grin

Here's some pics:

Motor - right side
Motor - left side

In case you're wondering', the solenoid is an idle-step-up for the A/C.

I know everyone says you have to have heat to the intake and you have to have chokes. Apparently that ain't true in Texas. The truck runs like a scalded dog and doesn't hesitate on takeoff at all.

It's your truck. Do it your way.

Cavebull, i would have liked to wait for the issue to be resolved, but Mr. Langdon hasn't responded yet.

BaldEagle, I gave away my one working Rochester B two weeks ago when a buyer picked up the 4400. I might have been able to take care of the issues I had with it by installing a fuel pressure regulator. More fool me.

But I was hoping to have the Holley Weber working within a week. I'm not there yet.

I have watched this post get lengthy and somewhat off point but have stayed out of it but now want to say a couple of things.
1.
I agree with all here that first giving a supplier every opportunity fo address a problem is the correct manner to deal with problems before coming here. So let's all adapt that as out procedure. No more explanations are neccesary so let's just leave it at that.
2.
I too have this setup and it's up there in pictures where all can see it. When asked I have often expressed my own opinion but won't now as it is already out there.
3.
I know Tom Langdon personally and am not defending him but his Stovebolt Engine Co. is a sort of partime thing as the guy is retired. Cut him some slack. He has gone to bat for me and helped with free parts when he didn't have to. Sure it took some time on accassion but after all he is retired. That is something I want to do also and having a Medicare card of my own I understand slowing down better than I did at 50 yo.
4.
I have suggested without success that a seperate forum be set for vendor bitchin'. I want to know who the worst are too and no one here wants to make a costly mistake. But we should have a Bitchin Room to go to for that sort of thing.
5.
As the guy with the Editing and Deleting authority I am extremely reluctant to use it. However I am always on guard for threads that get way off track or hijacked. That's just not nice. I do occassionally place a thread into the proper forum.
I try to be understanding of each members issues and concerns even when they are critical of me. But let's all try to limit the [censored], say what we have to say and leave it be. We are all intellegent enough here that we don't need things explained ad-naseum and I hope I spelled that right. Interesting thread gentlemen and ladies.

What you could do, since it's brass, is to solder them closed and then drill out to the diameter you need. Hardware stores have those miniscule exact-size drill bits.


How did you know that your jets were too large? Fuel fumes in the exhaust? Fouled plugs? I'm really curious, especially since I may have to do the same thing.

Did Holley say that there were no jets from other carburetors that would fit?

It was simple really. Black smoke out of the exhaust when I step on it. It came from Langdon's set up for sea level. I was at 5800 ft ASL at the time. So I had to lean it out.

Holley did say there were no other jets. That was the old Ford Pinto carb and when they were no longer used, Holley discontinued manufacturing of the jets. Really though, drilling them out is easy. But it's a very small, very fragile drill bit, so you have to be careful.

About Tom Langdon, I think it's wonderful the way he supports the hobby. He won't hesitate to call you back, and was always helpful. I really like the guy, myself. And if it weren't for his carb options, which are by the way really very inexpensive, the stovebolt engines would have that much fewer options other than the antique Rochester 1 barrels.

Just a vote of confidence here for Mr. Langdon.

I should have mentioned in my previous response, I bought Tom's electronic ignition and am very happy with it. I've spoken to him a few times on the phone. Like a lot of guys his (and my age) he has very strong opinions about carburetion and proper setup. I happen to disagree with some of what he says, but my decision not to go with his setup was based upon the look that I was going for and not any dissatisfaction with him or his products.

Like Dave says, the guy is retired, so his responses will sometimes be delayed. If you don't know that up front, your expectations might be incorrect.

I agree. I haven't been all that happy with this setup either for the reasons mentioned above. It seems I had most of these issues in getting mine to run. I think I'm close now. My point though is that Tom is very approachable and responsive. I liked working with him and appreciate his dedication to our hobby.

Unfortunately, after years of working as a consulting engineer, I have a phobia about talking to people on the phone. My cell phone has built up to nearly 600 minutes just from buying enough time to keep it from being disconnected.

Two more pictures at: http://good-times.webshots.com/album/564126102jBBKyv

I'm not sure if those URLs change or not. Anyway, the intake manifold is ready. Mounting surface cleaned up well enough, stud mounting holes tapped and chamfered.

Somehow someone managed to get one of the carb mounting studs in upside down and even managed to get the nut on far enough so that it looked like it was doing something. There was a perfect example of the right way to do it about 1 3/4 inches away. That kind of thing is why I don't trust old mechanics. I'm only 58.

Forget everthing I've said or didn't say about Tom Langdon. I'm sorry I mentioned him in the thread topic. He's probably a great guy. Whatever.

Two more pictures posted. The adapter is just about ready to go on the manifold. I'll have to bondo one casting error and still have to polish the bore. The gasket surfaces look pretty good, but I had to take off enough metal so the outer edges needed to be re-chamfered.

Well, I thought I made some progress today, but just ran into more problems. I added six pictures to the Webshots album Holley Weber Conversion

I got the bore polished . . . kind of. Unfortunately, the pits and zits lasted longer than my patience. I hope that it looks at least a little different.

Then I prepared to mount. Ooops. The studs are too long, so I'll have to buy a phenolic spacer and another gasket. That will make 4 gaskets, a spacer and the 1/4 inch aluminum plate. I hope I don't have to build a water heater for a carburetor that is mounted on a stock manifold.

Oh well. If it was easy I'd give up.

   Yeah your gonna have to have that spacer, did you let it go with the old Carb? If you want to trim the extra set of ears off the adapter it works good to mark it with that spacer and trim accordingly. Considering the amount of work your doing on it at this point you'll prob. kick yourself if you don't do that now. With the spacer and the supplied gasket, I had to hold each carb up about 1/4 (I believe) while I started the nut. Once the nut was seated completely on the threads I could set the carb down and tighten them down the rest of the way.

   From reading this and looking at your pictures, I'm wondering if the setup would have run just fine if bolted on the way you received it. I understand you have a high attention to detail and you expected that from the kit but this level of detail and polishing seems commonplace to me on top fuel drag engines or other high performance applications but have you looked at the inside of intake manifold casting on your old Stovebolt there.

KCMongo, actually I still have a spacer from a 1962 292 Rochester B, but I am just sick of this. I'm going to try to cut my losses and post everything except the carburetor body and part of the air cleaner in the Swap Shop.

I just can't find anything that fits my idea of a usable setup.

Someone is going to get a good deal, if they are silly enough to buy it all.

ok guys i wanted to wait until i had time to put my hw carb on
to comment further. i found the 1bbl to 2bbl adp. to be useable as is. the gaskets were thick and fairly soft and seal well.
i will rate putting the linkage kit on by looking at the supplied picture. as a three beer deal. and the hiem joint that someone
was worried about not having lock nuts well its not a hiem joint
both threads are right handed there for it can not unscrew so no lock nut needed. i will post my pics soon. philip.

These are Heim Joints They come in male and female. You should have received two females in your conversion kit, unless the kit is for something besides a 235 Chevy Six.

Take a look at Carroll Smith's book on hardware and fasteners, in the Heim Joint section.

Don't worry, I know that everyone else is a lot smarter than I am.

Hate to bump such an old thread, but hope to hear from folks that used the holley weber 2bbl setup.

I recently bought one from langdon's. Didn't have any trouble installing it and it is running decent (definitely better than my old Rochester) but I'm pretty sure I need a bigger idle jet for it. Can anybody tell me what size idle jet they're running? Mine is a 50 and I guess they come in 55 and 60 as well. I have a 230 inline 6 in my truck.

Reason I think this is that based on tuning instructions i've read, if you have to back the idle mixture screw out more than 2.5 turns to get it running nice, the idle jet is too small. I have mine out about 4 turns, in any further it struggles and runs rough.

Any info from folks using these carbs is appreciated.

thanks.

Idle jet: If it more than 2+1/2 out jet too small. Less than 1 too big. Good source for Holley Weber jets; Pegasus Auto Racing Supplies- 1800-688-6946. www.pegasusAutoRacing.com. The idle jet is only the beginning in tuning these carbs.

I picked up a Weber 32/36 at a swap meet a couple of years ago but was unsure about installing it on my 261 due to the negative responses I've read. I did take the time to do it now and couldn't be happier. Adjusted and jetted it according to info on websites. The truck is a 49 3600 with a 62 261. The engine runs extremely smooth, starts easier than ever and still plenty of power. Will give it more of a test come nice weather when I'll be pulling our vintage camper. So far I love it. Dave
