Replacing Carb on the Baja 5B and placing a new Walbro WT 813 

Will maybe make a video tomorrow showing how I replace my carb and place a new filter and starting that engine and making it BRAP!!
Walbro WT-813 high-performance carburetor. This is the carburetor recommended by Zenoah for upgrading your RC-style engine. Engines with the standard carburetor (WT-603, WT-668, etc) tend to experience a lag in low-end acceleration when tuned for peak power. The new carburetor includes an internal acceleration pump to allow faster recovery as throttle increases. Carburetor specs: Walbro WT-813. 15.88mm bore, 12.7mm venturi, independent tunable high and low speed jets. This carburator does not have an internal choke.
