New from GZR is the SS carb shaft upgrade kit. This kit will upgrade the stock carb shaft to a stainless steel high flow double notched on the back side for more bottom end punch. No more breaking or twisting your shaft, this will increase the air flow going through the carb which will increase bottom end punch. look at the pictures and see most of the parts except the shaft and end screws,throttle arm for it are all OEM walbro parts look around and you will see there is no kit like this on the market.

Please note this kit fits ALL WT style carbs  fits wt-257/1027,wt-1048,wt-990,wt-771, and all other wt series carbs
