44.7mm Piston Ring Kit For Stihl MS271 MS271C MS 271 271C MS261 MS261C Chainsaw Cylinder # 1141 030 2012

Saw runs good

The replacement piston works great in my MS 271. It wasn’t too hard to replace and my saw has been performing like new. I didn’t have to replace the cylinder, only had to hone it lightly. I’ve gotten many hours of sawing for a relatively small cost.

I picked up a burned up MS 271 (the style with the slip on rubber intake boot) for $50 and got this piston kit to replace the badly scored stock piston after removing all the aluminum transfer off the chrome lined stock cylinder. All in all, I had it fired up after a few hours of work.Key findings:- As with any piston and cylinder, you'll need to file your ring gap to spec. If you're rebuilding an engine, you probably already know this, but there are calculators online for figuring out ring gap of a two stroke based on the bore.- Run your fingers along every surface and look everything over for any possible machining leftovers. Mine had none, but it's always good to check.- Assembly lube! I slathered each bearing, the rings, and the bore with some oil to prevent metal on metal contact during the assembly process.- I'm not sure if it's needed, but I ran the first tank a little rich with oil to aid in lubrication during the first few heat cycles.I've now gotten a few hours on this piston and it seems to be breaking in just fine.

had to rebuild a stihl 270 this piston fit perfect saw ran like a top after rebuild would recommend

Worked well

Wish they offered a cylinder

This is the worst item I have purchased in my life very cheap made and wouldn’t recommend to my worst enemy. Rings don’t fit in piston groves .

Came scratched and with a chunk missing. Unusable, and now I have to wait for a refund.

Works great, saw is like new.

Attention ! Prendre les côtes exactes mais si on rien à dire cela ce monte Nikel 271

Easy to install
