Stihl 460 Magnum hotrod upgrade.
I bought this Stihl used with the nikasil 56mm top end upgrade. When I first got it; there were a couple of issues that needed fixing. There were 2 missing screws; one in the handle (should have been obvious), and one in the bottom. However, it started up and ran strong. This saw had 170psi compression; with out the compression relief valve, I don't think I could have turned it over! The first thing that happened was the gas cap started leaking, also there seemed to be a pinging in the motor, though it ran well with lots of power. I had a spare plastic gas cap and fixed that. I was running a mix of 89 octane (mid-grade) gas, that was recommended for my other saws. So, I bought some 93 octane gas to compensate for the higher compression the 460 was showing. After this, she ran like an angry grizzly. I currently have a 28" bar on her; but also bought a 36" bar for future use. I would recommend this saw for anyone. The only other issue I am having is spare parts. I have had a replacement air-filter on order for 6 weeks, and still have not got it. I also had trouble getting replacement screws for my MS391; it took me a month to get some replacement parts for it. My advise would be: buy an older Stihl (made in Germany), and stockpile some spare parts while you can, and you will have a saw that will last your lifetime!
