  1. All your videos are awesome. Thank you for posting this. Only thing I wouldve done differently is put a torque wrench on the 4 head bolts just to make sure the torque is even (without knowing torque value).

  2. hi dony,, so many people ruin a good chainsaw and trimmers,, blowers etc. by pouring raw gas in them,, this can easily be prevented by marking the fuel cans or? just take whiff you can smell the oil in the gas at least I can anyway or when you pour It in just look at it because its a different color usually blue or red just pay attention and it will prevent this from happening or another option just use the pre mix fuels in the cans- with 2 stroke engines some people just don't get it and I've never understood why? I'm 48 and been around these things since I was 12-13 years old and have not yet ever had this happen to me,its too easy to avoid

  3. Don, some advice. do not put a big bore (49 MM) on a stihl 029. I put a farmer technology 49mm big bore cylinder and piston in the 029 I was rebuilding. it ran fine but it likes to eat flywheels and will eat up their key in short order even though I decreased the crank and flywheel before they were assembled and put it on with an impact wrench. the big bore just has to much torque and compression for an 029. they failed when the saw was running and not on startup. one flywheel was the original one from stihl and the other from china.

  4. donyboy73? My Stihl ms261 needs a top end rebuild. I watch your videos on YouTube and want to ask what rebuild kit you suggest I put on it? Should I go with factory size or go big bore? Will that give me more hp?

  5. You made it look easy. Question: did you neeed to check the crank shaft and bearings before spending for the cylinder? Are the touque specs available instead of carefully tightening? Thanks for a great video. Steve, plymouth, MA USA

  9. Thanks to donyboy73 and his YouTube channel, I spent about 75 minutes this afternoon rebuilding the top end of my Stihl MS261 chainsaw. His tips and instruction were flawless and straight forward. Although he rebuilt a Stihl MS260, it wasn't too far off from mine. I had to do a few things differently and it took me a little longer than it took donyboy73. I finished the rebuild, mixed my fuel a bit on the rich side with 2 cycle oil as he suggested, took it outside and primed it to get fuel back into the engine, then pulled the cord a few times…and she started strong! AWESOME!!!! BTW, the saw repair shop wanted over $200 and I did it myself for $87 including specialized tools needed to repair my chainsaw.
