What is the air gap on a chainsaw?
Most chainsaws air gap is between . 2 to . 3mm, but you will need to check with your model’s manufacturer, as this distance needs to be precise.
How do you check the coil on a Stihl leaf blower?
- Place the Stihl tool on a sturdy work surface. Start the test with either a cool or a warm engine.
- Attach an automotive coil tester by placing the end of the tool with grooves over the sparkplug wire. Do not disconnect the wire from the sparkplug.
- Watch the coil tester when cranking the equipment.
What spark plug does a Stihl bg55 take?
NGK BPMA 7A
Stihl specifications call for either an NGK BPMA 7A or a Bosch WSR 6F spark plug. If you change plugs, make sure the boot on top of the plug fits snugly into place.
How do you test a magneto coil with a multimeter?
Pull the rubber casing off the spark plug. Set the multimeter into the ohms function, or just use an ohmmeter. Manually set the dial or button on the meter to the 40 k range. Do not use auto ranging, as it is unreliable with a magneto.
What is the spark plug gap on a Stihl leaf blower?
