Review on TOPEMAI 18mm Carburetor with Intake Manifold Air Filter for GY6 50CC 49CC 4 Stroke Scooter Taotao Engine - Optimized 50cc Carb, Moped Parts 50CC by Frank Villanueva

Very satisfied. Bought to replace my standard "tamper evident" Taotao carburetor. The first installation took about 30m with a lot of distractions. Now it takes about 5m to remove and install it. Mine was fitted with 33 pilot and 78 main jet engines. First I put it without adjustment and with a normal box and the scooter started immediately. I think it had a little more power, especially in the mids. I was concerned about running too lean with the stock jet and pod filter, so when installing the filter I also used a higher jet and worked down. First 88 (too bold), then 85 (too bold), then 80 (a bit bold). So I'll probably stick with 80, but the 78 jet that comes with the carb might actually be for a pod filter. It's at 1000 feet and 65F. Obviously, your results and nozzle performance may vary depending on a variety of factors. Overall, the carb gave me a slight boost in performance and an opportunity to tweak it. The air filter didn't make as much impact as I expected. I would tend to reinstall the airbox if the air filter is causing instability, but otherwise I like the sound. The elbow didn't seem to fit as well as my standard (possible air leak) and the vacuum hose was on the opposite side so I used the standard. I also tied an extra hose from the block to the frame. I'll be fitting a 50mm BBK soon so I'll see what kind of adjustment it needs.
