6 Holts Valve Grinding Paste Kit W/Stick - 70gm

Fuel combustion causes stubborn deposits to build up on the valves, which can prevent them from closing properly. This is made worse by modern fuels that lack lubrication. When the build-up starts to prevent a gas tight seal between the valve and the seat, they may need to be reconditioned, and you can do this with a Holts Valve Grinding Kit.
