How to tune a rev-limited chainsaw

[blsnelling]

Here's a video I made this afternoon demonstrating how to tune a chainsaw that has a rev limited ignition coil. On a saw like this, you can tune these by ear listening for it to 4-stoke. The rev limited kicks in before it gets to that RPM. It's very difficult to tell if your hearing the rev limited kick in or it it's 4-stroking. This is how you do it.
