Nice technique pulling the intake boot through with the string. They're stiff, I normally ended up folding it into quarters and stuffing it through.

[@SHONEY21Z]

That’s usually what I do and sometimes still have to even when using the string. You have to fight the urge to use a screwdriver haha

[@dichodichov6045]

Very nice skills you got there broski , keep making these. I wouldve loved to see more cutting i mean 32 min repair video and just 30 sec cutting 😂. Otherwise great content 👌🏽

[@SHONEY21Z]

Haha good point. I’m taking it out today to do a storm cleanup. I’ll take the tripod and post a video of the 260 and 360

[@dichodichov6045]

I’m waiting bruh, don’t procrastinate 😂😂

[@SHONEY21Z]

@@dichodichov6045I used it a little Saturday but it was pouring. Couldn’t get any good footage. Going back on Sunday to clean up. Should be dry. I’ll set up the camera and post a short most likely.

50:1 mix is what killed it. I know of a few stihls that were cooked using a thin mix, they were loggers so the saws really got used but a new saw should not burn out in 6 months. I have had a stihl 036 pro for almost 25 years and always used 20:1 mix for all my saws and it never had a problem except I did put a new carb on it several years ago and a new plug every year.

[@SHONEY21Z]

Today’s mix is pretty good. Studies show less than 40:1 actually makes the saws run hotter and less efficient. I mix mine at 45:1 to be on the safe side. But with the new oil technology, 50:1 is good as long as you don’t have an air leak or lean carb. But nobody ever blew up a 2 stroke running 20:1, that’s for sure haha

[@istra70]

Interesting but solvable. I bought brand new 661 and the engine is running beautiful, but they fitted the saw with 36 " bar heavier than the engine itself.... Every time I am lifting it - I am laughing.... Now i am looking for rollomatic lite bar ( extra unplanned cost ). I hope they can use the same pitch chain.... Thanks for posting ....

[@SHONEY21Z]

Nice saw! That’ll run sweet with a 20 or 25” bar. Matching the sprocket with the bar and chain shouldn’t be too hard. Good luck!

[@user-it1gw6oe9o]

Great video

[@SHONEY21Z]

Thanks my man

[@ChrisR]

Was it possibly run without the air filter or on straight gas?

[@SHONEY21Z]

It’s possible it was run on straight gas. No airfilter would probably lead to a dirty carb and non running symptoms. I don’t know the exact reason but I did find the one crank seal was worn and the case was packed with dirt. So it could’ve got too hot and run for a while.
