Mtd Black Parts

This secondary air valve gasket is an OEM replacement part that is sourced directly from the manufacturer for use on lawnmowers and other lawn and garden machines. The secondary valve is commonly known as the idle valve, and this gasket is used to protect the valve from contaminants and to keep the air and pressure at preset levels. If the gasket is worn or torn due to regular use, it will need to be replaced. If the idle on the engine is not functioning correctly, the engine dies when it should be idling, which is a good indicator of a secondary air valve gasket problem. If the engine idles too high, this could be another sign of problems with the gasket. Before replacing the secondary air valve gasket, drain the fuel from the machine and take the spark plug out to prevent accidental engine starting. Use the engine diagram to locate and remove the secondary valve gasket. Install the new gasket and reinstall the parts removed from the engine.This secondary air valve gasket is sold individually. It is compatible with lawnmowers, lawn tractors, and other small engines manufactured by Cub Cadet, MTD, Husky, Troy-Bilt, Yard-Man, and Yard Machines.
