Product no.: WT-990

Still in stock

Prices incl. VAT, delivery

Walbro WT-990 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.


  • 15.88mm bore,
  • 12.7mm venturi,
  • Independent tunable high and low speed jets.

This carburator does not have an internal choke. 
Note: This carburetor now comes standard with modified throttle shaft, so it will work perfectly in most R/C applications such as HPI Baja, FG Modellsport, etc.

The WT-990 Carburetor is the same as the WT-813 WITHOUT an internal acceleration pump.
