I hope the solenoid is the problem.
That's why I typically just sell them when it's a carb issue, or I get one that's new or know to be working. You can waste so much time messing around ordering parts, then trying to get the carb totally clean.
So it runs like an early husky 550

That's correct.
Boot and ignition coil were issues on the early versions.
Beefed up the cases on the 462. Also changed the piston/cylinder iirc.
My old 440 was a great runner, not the fastest, but it did whatever it was asked. But after running the 462's it was a no-brainer for a work saw and since I have a few 365/372oe's I have plenty of 70cc firewood saws. I feel the same in most the classes of saws, mtronic/autotune saws have a great time saving advantage over the earlier versions for jobs, but I still enjoy running them; even the rubber mount saws, just I won't run them as long.
Abuse can cause problems for sure, but I think many of the problems(especially starting issues) are caused because people don't understand what the problem is. Some things I like to do with the auto-tune/mtronic saws is to let them run a bit after shutting them off, and not to let them run out of fuel.
That seems to be a bigger issue on the earlier AT/MT saws though.
