Briggs & Stratton Springs
Engine springs maintain proper tension controlling critical engine functions throughout Briggs & Stratton assemblies. Small engine springs include governor springs regulating engine speed by balancing spring tension against centrifugal force, valve springs maintaining valve closure preventing compression loss, and recoil starter springs rewinding pull-cords after starting. Lawn mower engine springs feature various wire gauges and tensions depending on application—governor springs typically color-coded by part number, valve springs with heavier gauge wire for exhaust valves, recoil springs wound in metal retainers. Governor springs connect between governor arm and throttle lever controlling speed response. Broken or weak springs cause over-speeding, compression loss, or starter failure. We hold Briggs & Stratton springs in stock and sell worldwide.

Frequently Asked Questions
How do you identify which governor spring hole to use?
Governor springs connect between governor arm and throttle lever—hole selection determines engine speed sensitivity. Inner holes provide faster throttle response, outer holes slower response. Always note original spring position before removal. Engine manual diagrams show correct configuration—wrong hole causes surging or over-speed.
What causes governor springs to break or stretch?
Governor springs fail from constant tension/compression cycles, corrosion from moisture exposure, over-stretching during incorrect installation, or age-related metal fatigue. Broken springs cause uncontrolled over-speed potentially destroying engines. Stretched springs cause surging or inconsistent speeds—replace rather than reuse as spring tension critical for proper governor function.
How do you tell if valve springs are weak?
Weak valve springs cause compression loss, hard starting, backfiring, rough running, or power loss. Compression test shows lower readings. Visual signs include collapsed/sagging springs compared to new springs, or loss of valve clearance. Replace both valve springs during service as uneven spring tension causes valve timing issues.
Can you rewind a recoil starter spring without special tools?
Yes—secure housing in vise, remove old spring noting direction, install new spring through housing slot into pulley, manually wind spring clockwise to end of travel then back off one turn, hold tension while threading rope through pulley and housing eyelet. Wear safety glasses—springs can snap causing injury.
Why does my recoil spring break repeatedly?
Recoil springs fail from lack of lubrication causing rust, over-winding beyond spring capacity, worn pulley housing allowing spring misalignment, or damaged starter clutch creating excessive resistance. Clean and lightly lubricate spring, ensure rope length correct preventing over-wind, check starter clutch for binding—repeatedly broken springs indicate mechanical problem not spring quality.
