Universal Nylon Piston Stop Tool 2 Stroke 4 Stroke Engines 10 mm & 14 mm

This item is a well-made item. made of a heavy plastic material. use at your own risk. I used this item on my Stihl MS180, and it put a hole in my piston. the repair is costing me $200.00. I was told by a local Stihl repair facility they use the rope in the cylinder trick. it is safer I guess.

Doesn’t stop the piston. Completely useless and broke upon first use leaving it stuck in threads. Now I need to figure a way to remove it. Wish I never bought this junk

Work’s great. Used it for repairs on a couple chain saws. Threaded just fine into the spark plug hole.

This is an update to an unposted review. Had a problem with delivery, empty package. Turned out there were 2 packages, empty one was delivered to me while the other one was delivered to the wrong address (correct address on package) and the person kindly delivered it to me this morning. So it is not this dealers fault but Amazon delivery driver. The piston stop looks good. I like it being nylon, less chance of damage to piston top. Yes I would recommend this item.

smaller than expected and didnt work for my needs

Too short and/or too flexible; Stihl chainsaw rotates past TDC with little resistance even when the stop was fully seated.

Good product works well omit use of rope.

Only reason it is getting 2 stars is because it MIGHT work for other applications but I can guarantee this doesn't work for small engines. Didn't even get close to making contact with the piston.
