Product Overview
Replace a worn, clogged, or poorly performing carburetor with this 15mm Bing-style carburetor, designed for select Puch Maxi, Maxi Sport, Maxi Luxe, Newport, E50, MK, MKII, Murray, Kromag, and related 50cc moped applications.
The carburetor controls the air and fuel mixture that enters the engine. A properly working carburetor can help improve starting, idle stability, throttle response, and acceleration. If your Puch-style moped has hard starting, unstable idle, poor fuel delivery, sluggish acceleration, or an old damaged carburetor, this replacement carburetor may help restore smoother engine performance.
This carburetor features a 20mm intake-side inner diameter and 15mm air-box-side inner diameter. Please compare your original carburetor size, intake connection, air filter connection, throttle cable setup, choke style, jet size, and overall shape before ordering.

Fitment FAQ
Will this part fit my specific model and year?
This carburetor is intended for Puch Models: Maxi, Maxi Sport, Maxi Luxe, Newport, MK, MKII.; Engine Type: 50cc E50 Series Engines.; Brand Cross-Reference: Fits Murray and Kromag mopeds utilizing the Puch-style intake.. Key physical/spec details from the product data include Intake Side: 20mm Inner Diameter (ID) / 26.72mm Outer Diameter (OD), Air Box Side: 15mm Inner Diameter (ID) / 20mm Outer Diameter (OD), 15mm. Use the compatibility table and product photos together before ordering.
Do I need to match the OEM part number?
Yes. If your original part has a stamped OEM or manufacturer number, match that number first before ordering. For this carburetor, also compare the intake diameter, outlet diameter, flange/bolt spacing, choke type, throttle-cable connection, fuel/vacuum ports, and engine displacement. This is especially important for E50 models because similar model names can use different parts by year or trim.
What models or situations does this part not fit?
Do not order this carburetor for machines outside the listed compatibility, or for units with different intake sizes, cable/choke styles, flange spacing, jetting requirements, or fuel/vacuum port layouts. Do not rely only on the model name or engine size.
What should I check before ordering?
Before ordering, compare your original part with the photos and check the intake diameter, outlet diameter, flange/bolt spacing, choke type, throttle-cable connection, fuel/vacuum ports, and engine displacement. Recheck listed specs such as Intake Side: 20mm Inner Diameter (ID) / 26.72mm Outer Diameter (OD), Air Box Side: 15mm Inner Diameter (ID) / 20mm Outer Diameter (OD), 15mm. If any connector, mounting point, size, or year detail is different, confirm fitment before installation.
Swapped some bing parts over to this one but saw no issues with this carburetor.Works as intended
Swapped out my Bing 14mm parts to fit into this 15mm clone. I needed to use the old slide, slide needle, and idle screw. Then the carb worked great on my Puch E50 motor . This carb came out of a Kromag / Puch, and uses a different style slide, needle, and idle screw. I was able to use the new jet, and I drilled it out to the appropriate size for my setup. If this seems like too much trouble, and you won't swap parts, then you may not get a carb that will work on your setup, then again, maybe it will. I tried the new 15mm carb first as it came equipped, but the idle was way too low, and stalled easily. No adjustment of the idle screw made any difference, either with the new screw, or the old screw. The original slide has a different shape contour, and the new slide just wouldn't adjust to a proper air / fuel mixture at idle. Also it would cold start without choking it, so it clearly was getting too much fuel. The only fix was to swap the slide, and needle, and idle screw, then it worked like it always did before. Slides do differ, and your ped may need to have it's original parts installed in order for it to perform properly.
It’s cheap, about a third the cost of similar products found elsewhere that being said it’s about a third the quality, poor casting and I had a leaky bowl gasket on mine. But at the end of the day its a carb on the cheap.
