G'day from "Down-Under". We are trying to identify the carby in the attached picture. It is all br*** and "Made in U.S.A." is engraved on the float bowl also it says "AEX1" - that is all! It is currently installed on a 1925 French Amilcar. It is running rich and fouling spark plugs. We need to find out float level settings and other tuning stuff and would like to know who made it and what it came from. Could be Schebler? Could be Stewart, made by "Detroit Lubricator Company"? Could be Zenith? Any ideas welcome! Thanks.
I think I actually have the bare br*** body for one of those on my workbench, holding several small punches... I picked it up from a trash pile after a Hershey as just a nice piece of br***, and only later noticed that it had a venturi and was clearly a carburetor...I'll have to look into some elderly books and see if I can did up any information.
I found my carb body...surely a close relative to yours, just the main br*** part. Identical mode of construction, yours has a lump or two mine lacks. Mine is also made in USA, on other side "FA.I", last character is a straight line tha could represent 1, I, small L...venturi restriction circa 7/8-15/16, did not think to properly measure it while at home. I've been flipping through a 1915 Audel's Automobile Guide, a bit old for this search, and have not found any carbs like it, nothing at all so compact and neatly packaged on the main body. So...just start dropping that float in small increments and see what happens! Some have normal mechanical limiting on the central post, others have weight that can be varied.
Did a search using just the words br*** and carburetor on google advanced image. The carb shown on this page: http://www.boatdesign.net/forums/materials/epoxy-sealing-br***-carburetor-float-15540.html has some distinct similarities and might be a smaller relative. The choke gate and strainer shown seem to fit in well with the style of inlet flange both our carbs have... Anyway you can bring up pictures of a lot of br*** carbs and might eventually find it a name.
Schebler made an aftermarket only type FA carburetor. It was designed for use on 4 cylinder engines around 175 CID. Other than that, I have no information about the carburetor. Jon.
http://www.mtfca.com/discus/messages/50893/52718.html?1209685792 My body matches that in the exploded view exactly! Carbking comes through for the 8,974, 232th time in a row!
Seems like we had one on here several years ago that turned out to be a Tillison. It was the same basic style. That one has adjustable jets like the early Linkarts, I am going to guess that tillison had the same. it was common for carbs to be externally adjustable way back when. Other than wanting to know what it is I would just play with it until I got it right if it were me doing it.
Schebler A, quite possibly the carb in Amilcar, was covered in a book en***led "gasoline automobiles" in one of the sites I ran across...can't find my way back to it now. That source may ID the one starting this thread.
Great work guys and thanks for the suggestions! Bruce - the one on the boat-design site is a Solex, of a type that was originally fitted on the Amilcar by the factory. This Amilcar is nearly 2 litres, which is big for an Amilcar and although the little Solexes are fairly common, the big ones that would fit this one are like rocking horse poo. The 84 year old owner of this car had one once, but can't remember what happened to it! The FA Wheeler-Schebler certainly shows a "family resemblance" and suggests that it IS highly likely to be a Schebler model, although not the FA. The one in question has TWO mixture adjustments - one idle and one high speed. Also there are no markings at all on the top of the float chamber. This is also a straight side-draught design. I have attached a different view. Yes, I agree with comments about "fiddling" with settings - we have been fiddling for hours! There is a lot of slack movement in the float-level mechanisms and jets are a bit worn, which is probably why it is being so cantakerous! If we knew the exact make and model, we might be able to search for appropriate spare parts. We have found some bits from a Stewart (Detroit Lubricator) which are very similar, but not quite right and won't fit. There are br*** "bob-weights" that sit on the float and they have pivots that lever the fuel-flow needle up and down. This mechanism is not working correctly. Thanks for the suggestions about Tillitson and Linkart - never considered those - will search wider. All comments are gratefully received - thanks for taking the time!
