Stihl MS 261 Top End Rebuild | Step by Step Instruction

My 261 was having difficulty with hot starts. Compression test revealed low compression. Thus, I made a step by step instructional video on how to rebuild the upper part of the motor.

From what I could see your cylinder and piston did not look too bad I believed if you clean up your cylinder and hone it, polish your piston and install new rings the OEM equipment would work just fine. I would definitely run a 40:1 oil mix in your gas. The 50:1 is just for EPA regulations not for Saw endurance. You can check Richard flaggs KZbin site, he has a lot of tests on running different manufacturers oils.

AMSOIL is the best oil in my opinion... I am 14 and have a 261 C-M and many other saws and machines. That's what they all run.

Why use the decompression button its only 50cc

The reason the cilynder doesn't fit properly is because Stihl came up with gen 2 cilynder called slant fit wich is supposed to give a couple more HP and less cooling fins in aprox. 2016-17 . The gen 2 is almost available only from Sthil and was in there saws at the time of change giving a bit of weight lost and lower profile cost lots more $$ I have the gen 1 bought in 2014 with the straight cilynder. Very nice video!!

bad choice of cylinder kit! way too much cooling fin area removed. you should have bought a meteor kit. 1/2 the $ of oem kit. i did not have to do anything to the fins on the one i used for my 362. not sure on the 261, i used a hyway kit on that one. i had to remove some of the ribs on inside of cover and a small area of cooling fins. both saws i bought off ebay with blown top ends. i run synthetic at 40:1. used to run 50:1. too dicey
