CRAFTSMAN MOWER T110 Solenoid Clicking No Start

Engine Camshaft

The Automatic Compression Release (ACR) is a centrifugal flyweight on the camshaft that slightly lifts the exhaust valve during cranking to reduce cylinder pressure. On Intek engines, the ACR tab often shears or the spring loses tension, forcing the starter to fight full compression. Replacing the camshaft restores the mechanical decompression required for the starter's torque profile.

Valve Cover Gasket

Excessive valve lash (clearance) prevents the ACR from physically contacting the valve lifter, rendering the decompression cycle non-functional. Because the T110 requires precise valve clearance (typically .004-.006 inches), a new gasket is the required sellable component to perform the necessary overhead valve adjustment that resolves the starting stall.

Starter Solenoid

While the clicking indicates the coil is energizing, internal oxidation or pitting on the high-current copper contacts can cause high electrical resistance. This prevents the full battery amperage from reaching the starter motor, providing enough power to engage the solenoid but not enough to rotate the flywheel under load.
