🔧 Installation Tips

Right Tool for the Job: Use a high-quality screwdriver that fits the slot perfectly. A worn tool is the #1 cause of rounded carb screws.
Cool Runnings: Only attempt to replace or drain carburettors when the engine is completely cold to avoid fire risks and heat-seizing of the threads.
Avoid the Tape: Genuine tapered screws do not need Teflon tape or sealant. If it leaks, check the internal seat for debris instead.
