How to Identify your Westwood tractor

Frequently Asked Questions

What do Westwood spark plug colours indicate?
Light tan deposits indicate proper combustion, black sooty deposits show rich mixture, white/blistered appearance signals lean mixture or overheating, and oil wetness indicates cylinder or valve guide wear requiring attention.
What spark plug gap is correct for Westwood mowers?
Most Westwood engine spark plugs require 0.030-inch (0.76mm) gap, though specifications vary by engine model. Always verify gap with feeler gauge before installation matching manufacturer specifications found in operator manuals.
How often should Westwood spark plugs be replaced?
Replace spark plugs annually or every 100 hours as preventive maintenance to ensure reliable starting and optimal performance. Fouled or damaged plugs require immediate replacement regardless of hours to prevent hard starting.
Why does my Westwood spark plug keep fouling?
Spark plug fouling results from overly rich fuel mixture, oil entering combustion chamber from worn rings, incorrect heat range plug for application, or extended low-speed operation without full-throttle running clearing deposits.
Can I clean and reuse fouled Westwood spark plugs?
Light carbon fouling can be wire-brushed and plugs reused temporarily, but oil-fouled, cracked, or heavily eroded plugs require replacement. Clean plugs rarely perform as reliably as new plugs; replacement is best practice.
