Assisting your engine while not in motion, the Carburetor Idle Adjustment Screw with Spring is a vital fuel component. Located on the 2-stroke carburetor assembly, this component is tightened into the carburetor. This results in engines idle increasing or decreasing depending on how tight the idle screw is.
This is a Idle Adjustment Screw w/ Spring for a standard carburetor Part Number (See Parts Manual): 4-15.
Great Product I really like this idle screw. I haven't found any problems with this one and it hasn't fallen out like many of the others I used. Honestly, it is a great product.
Just what I needed Old one fell out while driving and this is what i needed and worked perfect.
