ada gsr carb

[titanicwed]

does anyone know if the ADA GSR 15mm carb has a 15mm venturi? OR is this the bore size?

I believe the stock TSI carb has a 13.5 mm venturi...and I was hoping the ADA carb had a 15mm VENTURI...but I think it may be just like the stock TSI?....

I believe this ADA GSR carb is a WYK 58 and the stock TSI is a wyk 33.

Can someone help clear this for me?

thanks

FYI. The venturi is the SAME as the stock TSI carb. The only difference in the carb folks is the little "low speed" (fuel mix) screw on top...has a bigger SCREW....not hidden under the rubber cap like onthe TSI. A simplt screw driver allows for easy low adjustment. You do not need eye glass screw drivers to adjust low. A nice convenience..otherwise....13.5 mm venturi. 15 mm bore.

You can however replace the venturi with a 15mm from Walboro. Couple screws changes it out. Adios.
