Hello sunbear, 👋 I have a few husqvarna saws, don't use them much. Echos have come a long way. Bought a cs 4910 from Charles Brisco last year and man dose it rip. I still collect other saws. Nice 445 you worked 💪 on. You and family have a safe 4th. 😉🦅🦅🦅☺️
A few months ago I had a 445 for a repair. The coil was bad. It was giving a spark, but on some strange timing - cold startup was always with a loud POP (detonation) and then almost no power in the cut. With new coil I got power in the cut, but I could not get rid of the detonation on startup. Did the same light mods as you showed here (muffler mod and removal of that plastic cover from intake). I also slightly bent the connecting rod that goes from carburetor to the butterfly for pure air intake. My reasoning here was to try to give the engine more mixed fuel and air, and a little less pure air. Did not do the timed comparison of cuts, but my feeling was that the saw then had more power (torque) in the cut.
@@homopit42 that’s a good ideal on the throttle connecting rod and I did not even think of that. I do think that the small amount of timing advancement helps it out and feeling a little stronger from it. I only filed away about a third of the key in the flywheel.
@@timkirkpatrick9155 thanks for the feed and I will see what is going on with the recording. I don’t have a separate mic and just use the iPhone 🧐. So maybe it’s going out.

@@RichardSivonen happy 4th to you. That Brisco 4910 must be a fun saw. 👍

Your mic positioning is still leaving you hard to hear. Or you need a better mic. Sorry for the abrupt feedback. Outdoors is not as bad.
