2010年6月10日 · Other than that the MS660 and the late model 066 were nearly identical. The old school 066 had some differences: the case is different, no decomp, it didn't have the poly flywheel, fuel tank was a bit smaller, there might be some …

2020年1月20日 · I assembled MS660 Farmertec clone kit last month and was glad all parts were there 100% and quality was good. The saw runs very well and has lots of power. As recommended by some members on this forum, I used Stihl OEM decompression valve and wrist pin needle bearing, as well as Hyway crankcase seal kit. Everything else is what came in the kit.

2011年1月3日 · Love my MS660! If your cutting wood under 30" then the 440, 441 or 460 would be a very good choice. 660 is great for big oaks and pine...cuts through pine like balsa wood :biggrinbounce2: 36" bar, full skip chain

2024年10月28日 · I have a MS660 that I have used for years with a 1/4 -20 holding one side of the cylinder on . Does not seem to mind. I repaired a MS201TC that had rattled the 5 MM muffler screws out with 12-24 a few months ago . Holding up fine with a tree service that could wreck an anvil with a spaghetti noodle.

2009年11月21日 · Here's a couple of shots of the stock ports. After the machine work the height of the exhaust port is 4° lower.....that's a good thing on the MS660. Care must be taken not to raise it any during the porting process. It's at 98° now.

2011年2月7日 · Well, at least this post is consistent with what I said back in Post #5. Maybe we are getting somewhere. I've set the high-end RPM on my "new" rebuilt MS660 at 13,400. It's idling very nicely at 2500 RPM with a 32" bar and chain on board. Seems comfortable there. No significant chain creep, and that's important.

2004年5月9日 · Steevo, I actually own an 066.  Mine's one or two years prior to the MS660 and I believe it's sufficiently evolved that the only change between them is the nameplate.  The muffler exhaust openings are a formed slot and tiny hole.

2018年5月10日 · I've had my 660 for about a year and a half now and it's been awesome. Bought it used from a big tree service. It ran very well, compression was about 155psi if I remember correctly, it was definitely higher than 150psi. Fast forward to last weekend, I was milling a 32" white oak that's 13'...
