Can someone tell me what model Walbro carbs are this size please?
Here you go Jim.Just click on each letter group and then to each carb.
Select the Series [Frontstep Customer Center 5 Frontstep, Inc.]
By looking at Gizmomotors site the WT 257,WT 1048 and the WT 771 must be the best carbs for an engine.
