Stromberg Stan Howe question or whom ever

Post by dmdeaton » Wed Apr 14, 2021 7:23 pm

My low speed jet is loose and rattles off set point. I was tired after running new engine in today in the shop. Collar seems to be loose that the jet sets in. I will take it apart tomorrow but figured I would ask tonight. High speed is fine. How is resistance held against the screw?
Thanks guys

Danny : The collar screws into the body and the jet itself has two spring loaded balls that are forced out into the recessions on the inside of the collar. If the collar is turning just tighten it up. If the tiny balls have seized up or the little spring is broken or rusted, you'll have to replace the spring or free up the balls. Not easy but certainly doable.

The collar is definitely loose. I wasn’t the one manning the carb adjustment as I was watching all other functions. This is a rebuilt engine startup. The fellow making adjustments said the collar wouldn’t tighten. Will it hurt to unscrew jet and pull out or will I loose the balls?

You can back out the jet and inspect it but if the collar won't tighten that's the problem. It's threaded into the brass main body but I've seen a few sheared off at the base probably from someone trying to over tighten it. Most Stromberg collars are the same so you might have to dig out the broken threaded section and replace the whole collar with another used one. I don't have any extras but Stan might. When you get it back together remember the initial setting is around 3/4 turns out from gently seated.

Will take the carb off and do some surgery getting the other end out

100 year old parts.
I've had a couple others do that, usually rock solid but old brass, never know.
I'll send you one.
I have probably 100 Stromberg carbs i've stripped for parts, those and the idle needles are gone on probably 1/4th of the ones i find, the high speed needle is gone from probably at least that many OFs and the knob setup is so hard to find that I actually make new ones as I'm out of old parts ones with the long thread like the OF takes.

I just made 6 the other day. Have to grind the tips on the rod. Make the knob etc. PIA fussy work.

I have not figured out how to make the holders. I'm thinking 3D printing.

The great myth that I have an unending supply of NOS parts is just that.

I'm well over 1000 OFs plus another 1000 other strombergs. Nos parts in short supply.

Can't find parts carbs anymore,

I'll try to get you one in the mail tomorrow. You can just unscrew the broken off piece out with an easy out or screwdriver, you can also solder the two pieces back together or send it back to me in pieces and I'll do it. They don't need to be very tight to work.

I wish I could figure an easy way to make some of them and also a less time consuming way to make the knob and threaded part. I routinely replace the balls and spring in the old ones and run a die down the threads but so many OF's are missing the needles ................. I probably have 20 or more cores missing parts. It is also surprising how quickly I run through a $45 stick of brass making knobs. I need a CNC machine or somebody who has one who doesn't have a $2000 minimum.

When I stated doing these 15 or so years ago a good complete OF core was $35. I passed a lot of them over because they were missing parts or the steel parts were rusty.

Who would have thought. Now cores are $250-300 for a mediocre one if you can find them. I am trying to find somebody to laser cut or water jet another 50 throttle arms and choke cable holders, they are missing or unusable on at least half of the ones I find. The guy who did the last ones for me got too old to work. I know the feeling.

The place I buy the needle and seat sets won't sell me more than 50 at a time because they don't have them in stock. They used to cost me $2.16 a set. Last ones I bought were about $6. 50 of them were right at $300

Easy way to get rich. Turn good cores into parts for other cores. Throw the $50 ones you bought to get parts off of on the brass pile. $3 a pound. I buy any core I can find with a good float cover and knobs and hope the float is usable and the float cap is one it although I make those by the handful. Not enough hours in the day and some of it I just can't make.

Its a never ending battle with this stuff. Thats why I try to snag some things as they go up for sale. I dont need them at the time, but when you do need it you got it. Did I say that right? :?

Yes you said it right! But! There comes a point, where too many of some things is too much. :lol:
I know the voices aren't real but damn they have some good ideas! :shock:

There would be a lot of people thinking L4's were good carburetors if I hadn't put some time and effort into Stromberg OF's, Zenith S4BF's and a few others.

Nobody else I know of invested any time or money into it.

Ever hear of a Mayer carb before I started buying them??

U and J's were ten bucks at a swap meet and didn't sell because every bowl was split.

Mayer looks somewhat like a Stromberg, doesn't it?

Danny, Since you don't have to adjust idle after you get it dialed in you could simply attach a wire or other method to prevent it from rotating until you find one of the barrel retainers. I didn't realize those round barrel types are so fragil.

I have plenty other things to do until parts get here. But not long and she will be on the road!
