Briggs & Stratton 65704S Breaker Plunger OEM Ignition Points Replacement

The Briggs & Stratton 65704S Breaker Plunger is a genuine OEM ignition component used in the breaker points ignition system of Briggs & Stratton small gasoline engines. Also referred to as a points plunger or ignition plunger, this small but critical part actuates the breaker points as the engine cam rotates, controlling the precise timing of the ignition spark.

Key Features:

• Genuine OEM Part — manufactured to exact Briggs & Stratton factory specifications for assured fit and function
• Broad Engine Compatibility — used on most 2–11 gross HP horizontal and vertical shaft Briggs & Stratton engines
• Replaces Legacy Part Number — direct replacement for superseded part number 65704
• Ignition System Component — works within the breaker points (contact points) ignition system to maintain proper spark timing
• Durable Construction — built to withstand the repetitive cam-actuated contact demands of small engine operation

This breaker plunger is a common wear item in older Briggs & Stratton engines equipped with conventional points-style ignition. Replacing a worn or damaged plunger restores accurate spark timing and reliable engine starting. OEM part number 65704S supersedes the original part number 65704.
