I picked up a few parts today, fuel line and filter, and a new air filter. Took the saw apart last week, cleaned every thing after tearing down everything except taking the engine apart. Got it back together this afternoon, and after setting the idle, it runs again! Screams a bit with the now opened up muffler too. While at the dealer I picked up a scabbard for my 20" on my 361. I like the new full length. Don't know why Stihl didn't do this before?
Just a word of caution, if it's "screaming" after a muffler mod, it may be running lean. Have you readjusted the H screw on the carburetor? If not, it will be in danger of overheating and seizing.
Used my saws today to do some cutting back in the forest. It feels good to cut again. It's still a pain getting back there with ice ruts and down trees all over the place. Had fun today though!
You are very corrct...the High screw usually does need "fattened" up after a muffler mod . ......But.......There are no High or low screws on the 017 , 170 , 018 , 180 . Only an idle adjustment . Makes it tough to tune right..so be careful . Thats why the WT-215 carb swap is so popular.......I have an extra new one if anyone is interested I ended up keeping the original carb on my 180....and I run about a 38:1 mix in all my saws anyway.....even the 50:1 saws . A little extra protection...no smoking issues... Seems to keep the lil 180 from screaming out of this world
I'm running Maxima K2 oil at 40:1. I would think a muffler mod in a 018 would be fine with that. The only thing I did was drill a 7/16" hole straight through it. I need to pick up a small piece of screen for it yet, now that I think about it.
This 018c does not have a high or low adjust. Just idle. It's a horrible thing and I hate it. I mean it's just not right, I feel cheated with carbs like this.
I would be curious to take an IR thermometer reading of cylinder temps before and after a MM on a saw like that with no carb adjustments possible. Remember, it's not the amount of oil we are worried about. Running lean creates heat and if that cylinder/piston gets hot enough, it won't matter what oil you are running or how much of it is in the mix. Two-strokes are gasoline-cooled after all.
