Wow that thing was running super rich there initially. You can hear it and see it, that was a real smoke show 😅 I think you're right, that thing hadn't been run properly WOT and and accumulated a lot of excess oil that we could see being burned off
Don't overlook the 545 mk2...it's an excellent saw and a lot of people overlook it due to the 550xp. I've run both and I slightly prefer the 545...it seems like it's a little less of a screamer on the high end but it's timed more for torque. Very powerful saw with a lot of torque for 50cc. My favorite saw...like it even more than my 572xp
I have an opportunity to get an used 572 XP, from 2019, for a really great price, but the current owner says it has restarting issues when hot. I tried it for a short time, it starts right away when cold, idles fine, accelerates without issues, it restarted fine there, but I could not try it in the wood at the owner's place. How hard would it be to diagnose and fix the restart issue?
