I looked around and this is the best for the price. I have likes and dislikes, Its starts super easy, the choke doesn't vibrate itself out of place, it is a good increase in filter size, and it doesn't stall out at low speed as much. Its jetted a little low for me, my top speed is 15 mph lower and I'm now at 22mph. For installation its pretty simple there is no need for instructions, just use the adaptor and pipe tape (tape up the inlet tube and put adaptor over and its good to install). AND DON'T OVER TIGHTEN IT, most people who own these bikes don't have mechanical experience and they don't realize no matter what your engine and all parts for it are probably Chinese so you need to just get it snug. And keep your old carb you might need to switch the cable holder. Review: Works great! - Arrived just as described. Everything works and it started up immediately way easier than the stock one. It has a really nice idle as well. Great carb. Not sure the power difference yet because I haven't gotten to ride it more than a couple of minutes. Works great though. I ordered the intake elbow to account for the bigger air filter as well. That's why you don't see it on. Fit. Perfect. ## Features - 19mm Carburetor With Filter: 58mm/ Color: Red and Blue - Fits 2 stroke 49cc 66cc 70cc 80cc engine With No Adjusting Throttle - The screw on the side of the carburetor is for the idle. - Jet: Normally for 6mm jet,you can start with Start with the smallest size jet, the jet does not need to be torqued down with a great deal of force. - Note:You have to wrap several layers of thread tape around it if you are replacing the NT carb that came with your 66/80cc bicycle engine, and if you are at a higher elevation you may need to change jet size for this carburetor to run properly. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07989QWFH | | Best Sellers Rank | #83,298 in Automotive ( See Top 100 in Automotive ) #311 in Powersports Carburetors | | Brand Name | MaySpare | | Compatible with Vehicle Type | Motorized Bicycle | | Customer Reviews | 4.0 4.0 out of 5 stars (1,947) | | Exterior Finish | Aluminum | | Item Dimensions D x W x H | 2.89"D x 3"W x 4.8"H | | Item Part Number | US-49CC-R | | Model Number | US-49CC-R | | Recommended Uses For Product | Motorcycle | | Specific Uses For Product | Performance,Power | | UPC | 729043161317 729043161331 | ## Product Details - **Brand:** MaySpare - **Product Dimensions:** 2.89"D x 3"W x 4.8"H - **Recommended Uses For Product:** Motorcycle - **Specific Uses For Product:** Performance,Power - **Vehicle Service Type:** Motorized Bicycle ## Images ![Racing Carburetor 2 Stroke 49cc 66cc 70cc 80cc With Air Filter For 2 Stroke Engine Motorized Bicycle RED - Image 1](https://m.media-amazon.com/images/I/61ctboFRm0L.jpg) ## Available Options This product comes in different **Color** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Best for the Price *by L***M on February 16, 2025* I've been trying to fix up all my toys for spring, ended up needing a carb.

The paper gasket between the carburetor and the throttle assembly popped out when I took it apart, but it came back together alright. There initially wasn't enough clearance between the stock intake pipe and the seat tube of the bike for the carburetor + air filter so I had to reseat my engine with the carburetor on it so that it would fit. The fuel outlet from the gas tank was on the opposite side of the fuel inlet on the carburetor, so I had to snag some extra hose to get it to go across. Compared to the stock carburetor that came with my engine, this one idles much smoother and doesn't stall. I can't say I've seen a gain or loss in power compared to before, my engine still needs to break in. This was one of the, if not the, cheapest option out of all the listings for this carburetor since it does not come with any other pieces other than the carburetor and the air filter. I'm not dedicated enough to these engines that I'd go and replace the jet in the carburetor, so the right jet size is up to you. I haven't seen any problems with the stock jet myself. ## Frequently Bought Together - Racing Carburetor 2 Stroke 49cc 66cc 70cc 80cc With Air Filter For 2 Stroke Engine Motorized Bicycle RED - sthus Black Spring Loaded Chain Tensioner For 49cc 66cc 80cc Engine Motorized Bike 2 Stroke Engine - JRL 32mm-40mm Black Offset Intake Manifold and Gasket for 49cc 66cc 80cc Motorized Bike Motorised Bicycle (Black) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/61546916-racing-carburetor-2-stroke-49cc-66cc-70cc-80cc-with-air](https://www.desertcart.com.ar/products/61546916-racing-carburetor-2-stroke-49cc-66cc-70cc-80cc-with-air) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-05-24*
