I bet it will work fine.I got the cylinder nice and smooth and ordered a hyway popup piston for the saw, we will see what happens. I'm sure it will blowup as I have never replaced one before but no guts no glory.
will a ms 261 cylinder kit work on a ms 271 with a 3 bolt intake

Thanks let you know how it turns out.
As I got into this saw more I found that the connecting rod on the crank was blue from heat closet to the crank and the bearing on the clutch side was shot. I decided not to use this crank and order a used but in good shape OEM crank from a 291. Make a long story short waiting on parts. 
Rods are blued from factory.
If bearing and crank pin not blue all good to go.

lol Bearing on the clutch side was shot, looks like I got a backup crank. This is funny in a sick way but I put the piston in backwards so I have to pull it all apart again. Don't know how though I was really careful, but I was wrong. Really getting a schooling on this project. Hope that 518 stuff is easy to cleanup.
Always is a big word, but normally. Have fun with it and learn. I do something dumb most every day, but I muddle through fixing a bunch of stuff.
Well, got the piston turned I did put it in backwards
still no spark coil maybe, but leaning towards the flywheel because the saw ran with the break on I found out and did a bunch of damage and got so hot it melted the clutch bearing ( this happens when you get a eBay special) anyway more research and parts I'm sure. I did say this was fun.
Well I'm about at a lost as a young boy can be. I tested the coils both of them the old one is 2.6 ohms the new is 2.7 ohms from the boot to ground, spec say's 2-12. I though it might be the flywheel and ordered a know good flywheel. Still no spark. I've checked the wires to the switch both clean no cracks or cuts. Does anyone know if the case has a ground I'm missing? I did say it was fun, but real close to making some kind of lawn ornament out of it.
