YAMAKATO Huayi P27-1D Generator Carburetor Kit OEM for Champion Predator Generac GX390 (420cc-459cc)

Overview

The YAMAKATO Huayi P27-1D Generator Carburetor Kit is an OEM standard replacement designed for reliable performance on GX390 powered generators and their clones. The 27 mm bore is paired with a 30.5 mm air intake and 52 mm center-to-center mounting holes, delivering a practical and precise fit for a wide range of units.

Designed for manual choke configurations, this kit is compatible with many brands and models, including Predator, Champion, Generac, Coleman and other GX390 based machines. Note that this is a manual model carburetor, intended for operator control rather than an automatic choke system.

The throttle spring kit is matched to the carburetor to preserve throttle control and responsiveness, ensuring a smooth transition from idle to power when needed.
