MS-460 smoked, then seized. What's going on?

Might be a good idea to wind one up with no load a few times a week and listening instead of sticking it straight in to something.

Maybe in my younger days...

OK, here's what we found: The darn limitter cap was left off the carb after the previous owner messed with it. This allowed the previous owner to come up with a bad fuel/air mix and, most likely, a run speed that was too hot for the piston and cylinder to handle. They're both badly damaged. I never touched the carb adjusters.

Parts, alone, are $400 plus about two hours of labor. So, I can pop for $600 and get a used saw that should be good to go, or I can spend another $250 and buy a second new 460. I'm going to think it over. Again, damn eBay! I should have spent an extra $39 to have the Stihl service center, here, check the saw out before I ever fired it up.

Save the put-downs, please. The saw ran well, as far as I knew, and it did a very good job for a good, long while without showing any signs of wear or tear. While I'm fairly certain that some of you saw guys might have sensed that something was out of adjustment right off the bat, I had no basis of comparison, except to my 440, and I knew that the 460 was supposed to be punchier. I'll be more careful now, you may rest assured.

Thanks to those who gave me good advice. I honestly do appreciate it.

Happy Thanksgiving to those who celebrate it. Enjoy your days off!

$100 an hour for labor? It better be good to go then..

BB piston and cylinder will get it back running for under 150$ time tax and shipping is looked after.

:agree2: This is an excellent opportunity to learn more about your saw. Installing a P/C is easy. You should also take this opportunity to check the rubber hoses and maybe install a carb kit. I would at least open up the carb to see what's what in there.

MS 460 rebuild

Seems like I saw a P/C for 115.00 in Baileys.
Even with 1.5 hrs labor @ 70/hr...that only 105.00 in labor.
New seals ... $50 ???
Total = $270

I'd say well worth it !!!!!!...and you should save more and install yourself, then get the guys at the shop to pressure check your work...that should run $ 0 - 35 depending on how mice they are. Usually they are pretty nice knowing you did the work yourself.
