Adjust the snowblower valve lash

Exhaust valve

The snowblower valve lash is the amount of clearance between the top of the valve stem and the rocker arm. Incorrect valve lash prevents the snowblower valve from opening or closing properly. valve lash is incorrect, the snowblower engine is hard to start, runs poorly and loses power. Premature valve failure also results from improper valve lash. Check valve lash after the first 25 hours of use and then every 100 hours. Adjust the valve lash if the snowblower engine won't start or runs poorly.

Replace the snowblower spark plug

Spark plug

The snowblower spark plug creates the spark that ignites the fuel, creating a controlled explosion in the cylinder to move the piston that drives the engine. The spark plug won't create spark if deposits build up on the spark plug electrode or if the ceramic insulation cracks. Replace the snowblower spark plug if it's fouled or damaged.
