cylinder

So, My Makita dcs520 has been a great saw up until the last few uses where i noticed it started smoking quite a bit on startup, it's been down on power and I've found it to be bogging down a lot when getting on the dogs. a cold compression test returned 70-80PSI which was much lower than what...

Hey everyone. I just bought this used 036-cylinder off eBay. It has some odd pitting, as seen from the pictures. The ad said no scoring but didn’t mention anything about the pitting. The pictures were too far away and out of focus to see the issues. My question is, would you run it, or would you...

I'm replacing the intake boot. Probably end up taking off the cylinder now also. So my question is on the second picture. There's a line on the piston and there's some metal on the edge of the intake ramp. Is this bad? Compared to tge new intake boot , the old ones mating surface gasket was...

I received these cylinder in a trade from a buddy. Was hoping to get them identified.

I recently rebuild my MS 360 top end using a Hyway jug and pop-up piston/caber rings. Ran the new top end for about 8 tanks, but it never really woke up. Compression did not feel high enough. I checked squish and it was .060 so I milled the cylinder plate and planned to do a base gasket...

Hey guys, I inherited this 372 X-torq with a broken piston. A chunk of the skirt on the exhaust side was broken off and there were metal shaving in the exhaust. The cylinder was badly scored. I went ahead and replaced the piston and cylinder with OEM parts. I broke in the new top end properly...

Hello guys, Time ago I have bought a used Stihl MS192 TC chainsaw. The TC version has the Easy2Start function in other words the cylinder has a pre-exhaust groove, which makes starting the saw easier. A friend of mine has the MS192 T version and I compared the effort needed to start each of the...

Hi everyone, I picked up a decent looking MS391 (PHO) on CL for $40, about 5 years old. The seller told me he accidentally straight gassed it. Thought he had put the oil in the 1 gallon can, then filled at the station, and the rest is history. He had bought it to mill with and it didn't seem...

Hey y'all, I have two ms-261's that are both showing some scorch marks at the top of the piston on the exhaust side. They still seem to be running well and have good compression (by feel not with a gauge), and I can't see any scoring in the cylinder or on the piston. My question is, now that...

I purchased a Craftsman (yes I know) chainsaw at an auction a while back. I've replaced the primer bulb, fuel lines, and filter. It's always been difficult to start but now I've got a new problem. When I go to pull start it - it has a large amount of fuel in the cylinder. I pull the spark plug...

Mucking with a used 066 Chi Cylinder. Suspect it is now a paper weight. Is plating gone??

I recently came across a NOS Homelite SXL 925 cylinder and decided to grab it. I take it out of the box and couldn’t help but smile (been so long since I’ve seen a brand new SXL 925 cylinder). My smile quickly fades when I notice the muffler threads shining back at me with a reddish/ copper...

Hello chainsaw experts, This is an VI 955 cylinder where the piston scuffed the wall and began to wear through plating at port edges. Would this present future problems, decrease longevity, or cause any performance issues? If okay to use, what should be done to minimize any negative impact? I...

This is the second time this has happened to me on this saw. The first time my dad put straight gas in it. It looks similar and I used acid and sandpaper to clean the inside of the cylinder and just added a new piston. It wasn't perfect but it looked pretty good. I am wondering if this...

I'm just bored with saws, and really don't have time to fool with them anymore, trying to keep my wife healthy. They are all for sale individually, for $55 shipped each. They are all "open box", some I've had for awhile, some are pretty recent. They are as-is, as I'm just cleaning off the bench...

Hi All, I'm new to this group. I wanted to know if anyone had a suggestion or ever had this issue before. Log splitter 9hp BS motor, 25ton Hydraulic Cylinder on the machine(The brand isn't known). As we were using it the oil started gushing from the piston area close to the cylinder. We...

Hi folks, I'm interested in the differences between the Chinese zenoah g5200 clones in the 45-52-58-62cc range. My understanding was that to upgrade lets say a 52cc saw to a 58cc, one would just have to switch piston and cylinder. In one thread, I read that replacing the crankshaft was also...

I have an MS650 magnum with a scorched piston (and possibly the cylinder) that I’m working towards repairing. Looking for OEM parts to make it right.
