Gizmo's Racing modified Walbro wt-257/WT-1027 carburetor. The 1027 is identical in every way to the 257 just renamed because it's now sold through Zenoah/Husqvarna
This carburetor is an EXCELLENT upgrade for many RC airplane, helicopter, car/buggy, and marine applications. The 1027 is identical in every way to the 257 just renamed by Zenoah/Husqvarna Works well on most Zenoah engines and clones. Substantially outperforms the stock WT-644 carburetor on Zenoah G231PUM / G260PUM engines.
