RE: Toro 25cc Weedeater engine
Hi M007GUNIT,
People have the best luck using a 11mm Walbro with two needles on the 25 to 30cc weedies. It will have a 28 cast into the inlet on the venturi. The most popular is the model WA-167. I'm using the WT-324's made for weedeater. The 28 equals 28/64ths which is about 11.11mm.
