MENUMENU
 

Bing Carburetors

Types: Carburetors for each type look and fit the same and share most of the same parts.

ID Numbers: These are just the known Bing ID numbers, mostly from USA-model mopeds. There are many more not listed here. ID numbers from different types can be similar, a source of confusion.

Nick Names: The names are from the most common 1970’s US-model moped that carburetor type is used on. Some of the nick names might be inappropriate, or downright goofy, for other places and times. Nick names are necessary because many ID numbers do not tell the type. For example, a 1/12/315 is a “Jawa” type, but a 1/12/314 is a “Puch” type, completely different.

10. Bing Service 

bing crownWelcome. Included here are Bing carburetors used on mopeds, originally sold in the US from 1960 to 1990. This is only a small segment of Bing. There are also Bing carburetors on mopeds not originally sold in the US, or from earlier or later times, and on most German motorcycles and power equipment.

These carburetor categories are nick-named after the most popular US model or make. The Sears Allstate moped had the same carburetor and engine as 1950’s and 60’s Puch MS50 series and Tomos Colibri mopeds. The Puch Magnum X small motorcycle carburetor was the same as on many other 50cc motorcycles, especially German.    

Bing moped carburetors, 10, 12, and 14mm, came on German (Sachs, Kreidler, Solo), Austrian (Puch, Kromag), and Slovakian (Jawa-Babetta, Manet-Puch) mopeds (US models). Besides the three venturi sizes, there are also different configurations and clamp mount sizes. Puch, Solo, and Kreidler Bings have round float bowls that screw on, and 3.5mm jets. Sachs Bings are square and “smashed up against a wall”, too close for any other carburetor to substitute, and have 4.0mm jets. Puch Bings have a 20mm ID clamp mount, and 20mm OD spigot mount for the air filter. Sachs Bings also have a 20mm clamp mount, and a two-bolt flange mount for the air filter and external choke. Solo and Kreidler Bings have a smaller 16mm clamp mount, and a large 53mm “bell” for the air filter to clamp to. Puch A-D Bings have a 23mm clamp mount.  

The model number, stamped on, tells the size and settings. Use the Puch Carb Specs Table below to find what jet number and other parts your carburetor originally came with. Then use the Bing Jet list or graph to find what jet drill should pass through. Then use that drill to clean the old jet and restore it to normal size.

Normally, carburetors appear first in the parts list. But Puch has over 30 versions. So they are here instead. Use this table to find your Puch carburetor’s original jet size and other settings, just by knowing the ID Number. Or use the applications and other clues to find what ID Number and settings that it originally had, if the original carb ID Number is not known or not trusted.

###### # ################################### ###### #########################

 

Above is a list of about 30 different Bing Puch carburetors. There are just two “carb bodies”,  12 and 14mm. But they can have different jets, needle jets, throttle slides, and throttle needles (different from float needle!).  Use the chart above to configure (change the settings) a carburetor for a particular model, as long as it’s original and stock. For example, you have a 1977 Puch Maxi with no carburetor. You have a 1980 Murray carburetor that looks identical. From the chart they are both 14mm venturi, but the jet needs to be size 64 not 62, the slide #24 not 51, the needle 1 notch not 2, and the needle jet size 2.22 not 2.12A. Change those four things, and change the stamped on number from 1/14/166 to 1/14/160, and you will have the original specification carburetor. Or if you have a scrambled pile of carburetors and loose pieces, you can make any original configuration carburetor from the chart.

There are always some (sometimes lots of) little things that make life difficult. Old engines with compression and/or air leaks will need bigger than original jets. Old engines with clogged exhausts will need smaller than original jets. Engines with the original air box removed or modified will need bigger jets. Engines with performance exhausts will need bigger jets. Engines with big bore cylinder kits will need much bigger jets. This chart says what jet your bike had when it was brand new, not necessarily what jet is correct for it in it’s current state.

The air filter 48 has a rubber spacer around it. This rubber becomes soft, making the clip looser. Then a bump or jolt causes the air box back half 47 to detach and soon fall off. That is why most are missing 47, 48, 49.

Sachs Choke Cable Trickery: Above, a Sachs Bing carburetor and air filter assembly. First the grey steel plate goes inside the white plastic box front half. Then the two M5x12 screws bolt it to the carburetor. Then the choke cable is fed through the box half, The choke cable spring is slid over the end of the choke cable. Then the white plastic choke plate, at far lower left,  is attached to the small barrel end of the choke cable. This is done with the choke cable detached from the lever at the handlebar. When it’s all hooked up, squeezing the choke trigger moves the choke plate forward, blocking off the air. Releasing the choke trigger causes the spring to pull the choke plate back away, allowing full air in for normal running.

“A” means slotted float and rubber tip needle.
No “A” means no-slot float and metal tip needle.

 

 

 

 

 

 

 

 
101 types channel the idle mixture under the slide. A deeper slide channel makes a richer idle mixture.
      Fill in the idle channel with epoxy to make the idle mixture leaner. Grind it deeper to idle richer.
  
104 types have an idle tunnel with a separate fuel hole. A bigger idle hole makes a richer idle mixture.
      But it is not removable and not easily serviced.
 
Remember that once the throttle slide is raised up (opened), the idle channel and (to a lesser degree) the jet needle have no more effect. At full throttle only the main jet matters, pretty much. 
 
Bing 14.5mm throttle slides

Left 3 have idle channels and jet needle holes.
Right has no idle channel and no needle hole.
The twin holes joined together are for the cable.

Slot Position angle is expressed as the time on a clock. All four slides above have the intake side at 12 o’clock and the engine side at 6 o’clock. Then from the bottom view, “Sachs” is at 3 o’clock, “Solo” is at 12 o’clock, “Kreidler” is at 10 o’clock, and “Sachs D” is at 3 o’clock. Slides that have the same diameter and slot position can interchange, in most cases. Other 14.5mm slides are “Jawa” (early Sachs) at 12 o’clock, and “Allstate” (early Puch) at 12 o’clock.

This carburetor is for low powered mopeds (mofas), case-reed-valve engines, that position the carburetor way down almost below the engine. The choke is remote, by cable. There is no primer (because you could not reach it if there was). Otherwise it is very close to the Kreidler Bing, with the same size Ø16 mount, Ø14.5 slide (but a different slot position), same float, float needle, float bowl, M5 idle screw, needle, needle jet, and M3.5 main jet (but different numbers).

Originally all metal, this carburetor and intake silencer was made for the early Sachs 502 vertical cylinder moped engine, 1,2, or 3 speed, kick start or pedals, from the 1950’s and 1960’s. The name Bing “Jawa” should be called Bing “Sachs 502”, since it fits those engines like a glove. Then Bing “Sachs” here should be Bing “Sachs 504/505 A”, to be more correct, globally.

There is no choke slide that blocks the air like on other Bings. Instead the primer holds the float down until gasoline overflows into the venturi. That provides the rich mixture for cold starting.

Jawa used this classic German carburetor from 1979 to 1983, only after it was obsolete, and only on their highest power 1.7kW models. Those were the 40km/h (25mph) Supreme 2, type 207-394 (Babetta 207-504 in Europe), and the 50km/h (30mph) Supreme 3, type 207-392 (X 30 207-385 in Europe). All other Jawa Babetta models were 1.1kW or less, 40km/h (25mph) or less, with a smaller 9mm Jikov 2909 carburetors.

Apparently most, if not all, of the USA models of “Supreme 2” and “Supreme 3” have the 9mm Jikov carburetors, not the 12mm Bing. Of about 20 Jawa Supreme 2 and 3, found on the internet, all had 9mm Jikov carbs. Only the two at left had 12mm Bings. Yet the Bing “Jawa” carb is in the later 207-300 series American Jawa Parts Catalog.

Allstate Bing Diagram

Here is a beautiful cut-away illustration from the Danish website veteranknallertklub.dk. The venturi is 12mm diameter. The curved pipe is about 13mm. The jet and jet holder are a single piece, like the Bing “early Sachs”. The choke cable and plate are the same as Bing “Solo”, with a “carb” end on the choke cable. The screw-on top cap is M18x1.0 thread and M6x0.75 cable elbow/stop, Ø14.5 slide with slot facing the intake (like other early Bings), and jet needle, are interchangeable with Bing “Solo” and Bing “Jawa or early Sachs”.

From the left drawing, sliced vertically front to back, you can see the little pin that locates the throttle slide, near where the choke cable comes in at. Like the other early Bings “Solo” and “Jawa”, the slot in the throttle slide faces the intake, so the throttle slides interchange (but not with “1970’s Sachs” and “Kreidler”). 

  
 

Puch used this Bing “Allstate” 12mm carburetor on the MS50 (Moped Stahlblech – steel sheet) series from the 1950’s to the 1970’s. In 1969 Puch indroduced the Maxi moped, with an all new carburetor design. That carburetor, called Bing “Puch” or “round Bing” was in use from 1969 to 1986. It is way more familiar to Americans because of the moped buying frenzy in the late 1970’s. In the early 1980’s Puch developed their advanced technology future moped. But sales were down, and something like internal fraud contributed to Puch going out of business after over a century. If they had kept going, we would have an abundance of parts for the Bing “Austro Daimler” carburetor below.

Steyr-Daimler-Puch was so proud of the replacement for the Maxi, that they named it after their hand crafted performance bicycle line, and their 1899-1934 Austrian automobile name, Austro-Daimler. Not much on the 1984-86 Puch A-D was the same as the elderly Maxi. These Bing “Type 18” 12mm carburetors (18/12/206 and 18/12/207) are 1990’s technology. Notice the light throttle spring, possible with modern nylon lined cables and low friction throttle parts.

A Bing “Type 18” 14mm carb (18/14/180) was also on the 1995-96 Manet-Puch Korado.

A Bing “Type 15” is the same as “Type 18”, except it has a 55mm bell in front, for an air box.

Bing 17mm replica carb for Puch Magnum X

 

 

The Puch Magnum-X was a off road mini-motorcycle. It had a moped engine, but was not limited in power and speed like the street-legal mopeds were. So it had a bigger 17mm carb instead of 14 or 12. It looks like a Kreidler Bing, but is larger.

Bing Magnum-X cut away

 

Here is a beautiful cut-away grey-scale illustration, from the Danish website veteranknallertklub.dk. This “Magnum X” type Bing has the all-metal float needle, not rubber-tip push-pull type 15. The float has no slot because it only pushes on the needle. The Puch Magnum-X Bing above has the rubber-tip float needle that has a T top that slides into a slot in the float. On that kind, the float can push and pull on the needle. The all-metal type is on older Bings, in general.

This older Bing has a screw-in idle air jet 33. The Magnum X version has a pressed-in idle air jet, not replaceable. This helps to break up the liquid gasoline into smaller droplets, like a mist.
