I just got my MS180 that I bought for $150. It has normal scuffs from use, but is the cleanest used saw I've bought. The piston and cylinder look like brand new through the exhaust port.
I fired it up and put the tach on it. 14,700, bone stock!!! That surprised me, to say the least. I immediately yanked the Zama carb and threw on the WT-325A. I made no adjustments. It idled good, a little lower, and had great throttle response. The Walbro only brought it down to 14,400. That little of a difference could be in the LA adjustment which I didn't touch. This carb doesn't richen it up much at all. Maybe that's all it needs. I don't know. I'd love to have a fully adjustable carb.
Later this evening, I'll use the spaghetti method and measure the exhaust port and see where I need to go. The factory muffler is very open inside, so no need to uncrimp it. It's a straight shot to the front of the muffler.
Mine does not have a cover like on Mitymouse's 180. I'll just drill a whole for now and see about getting a cover later. Also, I already have a hole through the handle.
This saw sounds like it's totally leaned out even at 14,400, let alone at 14,700 with the stock Zama carb. There's no burble to it at all. However, when I pull the plug, it's pretty dark. I just don't want to fry a nice little saw that already screams in stock trim.
