Someone wrote that the correct rebuild kit is the K10WAT. In fact, it is the K20WAT. The carburetor is a WT-409A. If you check the listings of various parts sellers. you will see that the WT-409 requires a K20WAT rebuild kit. I purchased a K10WAT and found that the gaskets and diaphragm were correct but that the supplied needle was way to big.
Now, a few questions:
The carb is stamped with the model number WT409A and also the number 814 elsewhere on the body. I can find listings for WT409 but not WT409A. Anywone know what the "A" means?
There are orange plastic screw or screw caps for the high and low speed adjustments. Are these caps? Can they be removed?
My problem is that the machine will not run slowly and even when running fast tends to stall as if it ran out of gas. I rebuilt the carb but nothing change.
