Cool 3 wheeler Carbs

[Orangecnty250r]

Well I have finally cracked open the tote full of carbs for restoration. I found this one today. Had no idea it was in there. Has anyone ever heard of this one? I googled it and didn't come up with much other than it could have been made by the Edlebrock corp. I have a very special race project that this will be perfect for!!!

Has anyone heard or seen this before? Does anyone else have photos of other unique carbs???

[John_Neary]

that is cool, first time ive ever seen one. about the weirdest carbs ive ever used as a blue Lectron and a green Dellordo but i do not have any photos from when we used them

That's a Edelbrock Quicksilver carb they came out around 2000.

I have never tried one, but heard the are very difficult to jet properly across the board & have float issues on a off road application.

I think they are made by Weber for Edelbrock like most of their carbs are.

Duncan has some tuning info on their site about 3/4's of the way down the page.

Remember the Blue Magnum Carbs?

They were in a old 3 wheeler magazine carb shootout.

Remember the Blue Magnum Carbs?I remember seeing those carbs at an off-road equipment show back in 1985 or 86. They just looked like a hunka, the way they were built & painted blue. Their packaging didn't help matters either. They were shrink-wrapped to a piece of cardboard, exactly like a clutch lever would be, and hung on a "profit-rack" type display stand, like a bag of Cheetos.

Yeah, kinda strange and a interesting shade of blue they were made by Red Edmonston under the name EI Blue Magnum Carbs, here is some info plucked from the internet, he designed the Lectron carbs and a few others too.

Red Edmonston History
Since the beginning of the combustion engine, man has had a natural desire to get as much power out of the wide variety of motors manufactured for work and play. For the past 37 years, William “Red” Edmonston has chosen the motorcycle as his passion for power and speed.

Red started racing Triumph motorcycles in the 1940’s and after 13 years of racing and breaking bones, he decided to move to California and work with Triumph as a road manager as well as open a Honda dealership to provide for his young family. During the 1960’s, Red continually became frustrated with the fuel delivery systems for the motorcycle industry. Most of the carburetors being manufactured and sold on motorcycles were complex to tune, and required a constant effort to keep tuned for proper operation of the motor. This was primarily because of the multiple and overlapping circuits (different jets for the differing throttle positions) that caused the air fuel mixture to be very rich at different throttle positions. These early carburetors could not adapt for altitude changes either, which added to the constantly differing air-to-fuel ratios and tuning problems. Besides the frustrations that many had with keeping their motorcycles running at optimum, these crude fuel delivery systems also cause the motor to run very inefficiently and with significant harmful emissions.

In the late 196o’s, after many years of racing, managing race teams, and selling motorcycles, Red began his long career of inventing, designing, and manufacturing carburetors for the motorcycle industry. In short, Red has had a significant impact on the motorcycle industry over the past 40 years. Red has held nearly 100 patents and has invented and manufactured nine different carburetors, each of which has shared some similarities while each subsequent model continually added improvements in functionality and performance. The history of the Red Edmonston’ carburetors spans many years and a great deal of experience and improvements:

· 1968-1969: The Lake Injector prototype and final production model carburetor.
· 1970-1971: The Pos-A-Fuel prototype and final production model carburetor.
· 1971: The Pos-A-Fuel with remote float bowl production model carburetor.
· 1973-1974: The Lectron prototype and final production model carburetor.
· 1976-1977: The E.I. Prototype and final production model carburetor.
· 1978: The Blue Magnum production model carburetor.
· 1980: The Bank of Four Blue Magnum model carburetor.
· 1981-1982: The Qwik Silver prototype and production model carburetor.
· 1982: The Qwik Silver Bank of Four carburetor wins Daytona super-bike race.
· 1993: The Qwik Silver II production model carburetor (sold to Edelbrock).

Red has always been intrigued by speed and power in the motorcycle industry and his insatiable desire to continually improve on the fuel delivery to the motorcycle engine has benefited a very long list of motorcycle enthusiast and racers. The complete list of racing careers that have been enhanced would be far too long to mention, but some of the more prominent names of racers that have won championships with Red’s carburetors include Kenny Roberts, Eddie Lawson, Freddie Spencer, Ricky Graham, and Doug Domokis.

With such a long history of invention successes and countless motorcycle world championships being won with Red’s various carburetors, one might think that Red would be content to finish his career on top with the sale of the Qwik Silver II to the well renowned Edelbrock Corporation.

yeah that is the "blue Lectron" we had, i do not recall us getting much use out of it but it looked cool sitting on the workbench

[onformula1]

I may be the only one...:lol: but I love these carbs.

Dellorto magnesium 38mm

Once set up this carb runs great in a variety of elevations & temperatures

Very Interesting!!

I just restored one of those BINGS

[onformula1]

Mikuni TM 38mm

Pretty cool carb, zero idle, no main jet.

It is tuned by needle height, diameter & taper only.

Very under rated carb, great top end when tuned. Unfortunately it was squashed by the awesome Keihin PWK before it had a chance, many dislike them so like new carbs can be picked up for cheap.

AMAL from Spain, fun carb 38mm-44mm

Fun on a built 500cc 2 stroke on methanol for high climbing, dirt/sand drags and dunes.

I just restored one of those BINGS

For what bike or trike?

[HairyJR]

Found these in my spare parts/misc stuff last summer, 23mm and two 29mm carbs. Used the middle one on my ATC110 - 205cc alcohol motor running 20% nitro racing up Glamis competition hill 1980/81.

These are "Posa-Fuel" carbs, also found the invoice when I purchased the 29mm carb from H.A.P.I. Engines Inc. Calexico Int'l Airport, Calexico, CA. I think they where used on Ultra-Light engines at the time.

Thanks for sharing, I don't remember those, but I was about 7 at the time.

Still has the 110 throttle cable attached! :)

Seems like there is some more info about the OP carb. Based on this site and the photos, it looks like the one they describe which came on a XS650 Yamaha road bike. Personally know nothing about them though.

Cool...the little flag decals make it perfect for a unique tiger project. !!

Here's a few Keihn & Mikunis, the small mil is from my tri z. There's 2 38mm Mikunis that look similar but there are some differences. I took one off an 1981 300 aiR hammer and the other ones off a Tecate.

I had an ATC90 once that was missing the carb when I bought it. A 10 HP Tecumseh carb actually bolted on and would kinda "run". Does that count? haha
