Product Overview
Restore smoother fuel delivery and throttle response to your 2-stroke scooter or moped with this PHBG-style 17.5mm carburetor.
Designed for many compatible 2-stroke 50cc to 100cc scooter and moped engines, this carburetor can be used as a replacement for an aging, clogged, damaged, or underperforming original carburetor. It may help address common fuel-delivery issues such as hard starting, unstable idle, poor acceleration, hesitation, or inconsistent engine running.
Built with an aluminum alloy body, this carburetor is designed for durability, heat resistance, and corrosion resistance in regular scooter and moped use. The 17.5mm intake-side diameter makes it a common choice for small-displacement 2-stroke engines and light performance upgrades.

The GOOFIT PHBG 17.5mm modified carburetor is a useful replacement or performance upgrade for 4-stroke 50cc mopeds and scooters. With the slightly larger 17.5 mm bore compared to stock carbs on many small bikes, this unit tends to deliver crisper throttle response and smoother acceleration, which riders will notice in everyday riding and stop-and-go city traffic.
The included seal replacement helps ensure a snug, leak-free fit on installation, and the overall build feels solid for an aftermarket carb �� not flimsy but not premium either. Jetting is generally close to where most machines need to be, though some fine tuning after install (especially in varied climates or elevations) will help get the best performance and fuel economy.
Installation is relatively straightforward for anyone familiar with small engine carb swaps. The performance improvement is real for most stock setups �� smoother idle and quicker pick-up �� but don��t expect race-level power gains on a 50cc engine. It��s more of a serviceable replacement with a mild performance edge.
Overall, this carburetor offers good performance and reliability for the price. A solid pick if you��re replacing an aging stock carb or want a small, noticeable throttle improvement on your 50cc scooter.
Like all new carbs, some adjusting for your altitude is needed but ready breezy to do following one of a hundred YouTube tutorials. It was clean, no debris from manufacturing. A nice upgrade for the 50cc
It gave me nice fuel delivery fuel bowl never runs out and the low end power while accelerating is smooth and strong. Also love the that it has a pinch bolt style mounting just like the stock carb does
