Idle screw for TM32/34/38 carburetors by Mikuni (manufacturer part number 603-16003). This replacement part is designed for TM series carburetors in sizes 32, 34, and 38, allowing for fine adjustment of the idle speed during maintenance or refurbishment of the carburetor.
Designed for riders who are keen on maintaining a healthy fuel mixture, this idle screw facilitates the tuning of the idle and the control of the throttle in the closed position. Essential after cleaning, needle replacement, or gasket change, it helps restore stability at low RPM and provides a more predictable response to the throttle.
Before ordering, please check compatibility with your carburetor. This screw is aimed at DIY enthusiasts and workshops performing carburetor maintenance: disassembly, ultrasonic cleaning, mixture adjustment, and idle tuning. A small part that often makes a difference for a smoothly running engine at idle.
