Ignition coil/high-voltage coil components for STIHL MS070/MS090 series petrol chainsaws

Is your large, classic STIHL chainsaw hard to start, has weak or irregular sparks, or won't start at all? This is likely due to a worn ignition coil (high-voltage coil), an internal short circuit, or a damaged spark plug connector. This high-quality ignition kit was specially developed for large, classic chainsaws like the STIHL 070, 090, MS070, and MS090 and restores reliable and efficient ignition to your machine. Here's how the ignition system works: The ignition coil (high-voltage coil) converts the low voltage generated by the rotating magnet in the flywheel into a high voltage of several tens of thousands of volts. This voltage is then transmitted via the spark plug connector to the spark plug, where it creates an electric spark in the cylinder that ignites the fuel-air mixture. The proper functioning of the ignition system directly affects the engine's starting performance, power, and fuel consumption. Key Features: Electromagnetic parameters meet original specifications: Primary resistance, secondary resistance, inductance, and other electromagnetic parameters of the ignition coil are strictly designed according to original equipment standards. This ensures perfect compatibility with the flywheel magneto, precise ignition timing adjustment, and sufficient power. No adjustment required: Thanks to the fixed mounting holes, the electrode gap remains virtually constant after installation. Only minor adjustments to the gap between the coil and flywheel (typically 0.3 to 0.4 mm) are necessary, eliminating the need for complex ignition timing adjustments. High-pressure silicone cable: The high-voltage cable is made of high-quality silicone, resistant to high voltage, high temperatures, and oil contamination, and offers excellent insulation properties to protect against voltage drop. Spark plug connector with damping resistor: The spark plug connector features a damping resistor that effectively suppresses electromagnetic interference from the ignition system. This protects the user's communication devices and extends the spark plug's lifespan. Safety locking mechanism: The spark plug connector features an internal safety clamp or elastic flange that ensures a secure and reliable connection to the spark plug and prevents loosening even under strong vibrations.
