New to forum been around saws a good bit but haven’t gotten into modifying them any before. Just bought a new Husqvarna 545 mark 2 auto tune. I’ve heard of people modifying the older saws is it even possible with the auto tune saws to modify them for better performance?

I don't know about the mk2 but others have said a muffler mod really wakes up the oe version. I have a version 1 but haven't had a chance to do the muffler mod yet. It's a great little saw.

Thanks. How much, about 20 thousandths off the key?

I do not recall but that is probably sufficient. Better to start off with a little and you can always add more.

Do a muffler mod and timing advance and you'll be very happy.
Sorry if this sounds like a dumb question but how do you advance timing on a saw? I’ve ran saws since I was 13 I’m 34 now just never worked on them no more then carb cleaning and changing spark plug. Modifying them is a whole new ball game for me.

Only dumb questions are the ones not asked. You remove the flywheel and file the key to allow you to turn the flywheel counterclockwise. Measure the key before you start and file about 20 thousandths off of it. I hope this helps, hopefully you will get some better answers than mine.
